The Middle Ages and the Middle Stone Age – rock crystal tools and stone walls

At some excavations you do not really know what you are finding until you are done in the field and in a warm and cosy office again. Rescue excavations of Mesolithic sites can be like that. There might not be much stratigraphy and resources in the way of time and money are sparse. One digs out 50x50x5cm squares and the spoil gets wet sieved for finds and botanic remains.

The excavation of Hospental-Moos was a bit like that. The Urseren valley, between Andermatt and Hospental in Central Switzerland, is being re-landscaped into a holiday resort and golf course. The valley floor – ca. 1500 masl – lies at the crossroads to the Furka, Gotthard and Oberalp-passes and has long been an important valley on routes connecting various parts of the Alps. I already briefly wrote about the 2010 building brief and the partial excavation of a Late Mesolithic site (Hospental-Moos). Now it looks like we will be able to analyse and hopefully publish the results of the fieldwork as well.

Most post-excavation work will flow into the metal finds and the excavated Mesolithic site. Last Friday, I met my colleague in Zug to have a first viewing of the finds, in order to organise the post-excavation work. A large part of the affected landscape was searched with metal-detectors. The metal finds seem to spread chronologically across at least two millennia and a first look the finds-map shows how widely these are spread across the valley floor. At the same time, already now some patterns seem to be discernible. These finds will need to be stabilised and at least those that will need to be included in more detailed post-ex work will need further conservation.

The Mesolithic finds seem to date to Late Mesolithic (around 6000 cal BC). I already expected it, but it was only when I had finished a first artefact count, I truly realised what a fantastic site it is! Due to considerable time pressure, we did not do much on-site analyses and some of the excavated earth was only screened in the lab, after the actual excavation had long been finished. So, to some extend we really did not know what we were finding. The artefacts are almost exclusively made from rock crystal. It is a beautiful material, but from the point of view of a lithics analyst, they take some getting used to. They come almost exclusively from the excavated site. Only a few were found at various locations across the landscape.

So, I am very much looking forwards to the post-ex! For most of us involved, this is a bit of a side project, so it will draw itself over the rest of the year. I will write more when we really get going. At the moment I am excavating part of the Medieval and Early Modern remains of a small city in the south of the Canton of Bern. Very different! I will write more about that soon. You are also welcome to follow my Twitter feed: look for #Unterseen.

Dingos, lynxes, stone tools and the wilderness downtown

After almost two years, I’ll be visiting my hometown again soon. I live and work as an archaeologists in a country in Central Europe where I did not grow up. I was reading John Bradley’s “When a stone tool is a dingo: Country and relatedness in Australian Aboriginal notions of landscape” the other day. Bradley manages to illustrate and summarize some important points about how past (and present) societies might understand their surroundings much less compartmentalized as we in western societies of the 21^st C might do. It made me wonder if the concept of a lithic tool being a dingo can be translated to the (peri-)alpine Central European Mesolithic. Could a stone tool be a lynx instead?

However, intuitively the first thing that came to mind reading about such a complete/holistic worldview did not concern the Mesolithic, but my own life. More than a third of my life I have now spend away from where I grew up. Those ca. 13 years were spend in 6 cities on two continents. All of these cities have grown dear to me, but none of them I know as well as the city I spend my younger years in.

A. Deusser - Arcen von Westen (Lottum, von Arcen aus gesehen, mit Bodennebel, Abendlandschaft an der Maas, Lottum, 1918 - 1924.)
Deusser moved to the region I grew up in, during the 1910s-1920s, living and painting in Arcen.

One of the band members of Arcade Fire went back to the neighbourhood he grew up in and wrote the song “We used to wait” about this. Chris Milk and a team from Google made the interactive video The wilderness downtown around it, taking you back to YOUR youth. It is an amazing experience and shows what is possible with HTML5. It’s worth a try (best with google chrome).

My understanding and knowledge of the part of Europe where I spend the first 19 years (and a few more later on) of my life goes back at least four generations, roughly 120 years. It is probably the most in depth and intense knowledge and understanding I will ever have of any part of the world. I guess this will be true for most if not all people who pack up their things and go and live in a new part of the world. Perhaps I will look back at this post in 20 years and think how wrong I was. But maybe archaeologists, dealing with the material and immaterial remains of the past (and present?) in our surroundings find it easier than many others to find stone-tool-dingos – or lynxes – in their newly adapted homes.

Central alpine Mesolithic and threats to alpine archaeology – the summery of a presentation

Every year on the second Friday of March about 150 Swiss prehistorians gather in Bern. This year they were made to look at, amongst other things, the red dots on the map be below. I made this map for a presentation Th. Reitmaier and I gave at the yearly meeting of Swiss Prehistorical Society (AGUS). Since the 1980s quite a few Mesolithic sites have been found in the central Alps of northern Italy. Until the beginning of the 21^st C hardly any Mesolithic sites were known in the Swiss Central Alps, however. There is Mesocco Tec Nev, of course. And many sites are known further west in the Cantons of Fribourg, Vaud and Wallis. Since ca. 2000 the map of Canton Graubünden in southeastern Switzerland has slowly been filling up as well. As in the Italian Central Alps, many off the sites are found above 1800masl and many date to the 8^th and early 7^th mill BC.

We presented the site of Bergaglia, Val Forno-Plan Canin. Amateur archaeologist K. von Salis discovered a few chipped stone tools and charcoal in the steep sides of a hiking trail going up to the Fornoglacier and the Murettopass. The trail already had cut through it and threatens to erode it further. To establish the nature of the archaeology and its state of preservation we placed two test-trenches over the two find spots, which were ca. 8m apart. In each of the two test trenches a multi-phased hearth was found, dating to the late 8^th and early 7^th Mill. BC. A further find probably dates to the early fifth Mill BC. While earlier Mesolithic (Sauveterrien and Castelnovien) finds are common, not many sites dating to the latest Mesolithic and especially the earliest Neolithic are known in the sub-alpine and alpine zones of the central Alps. A further hearth dates to the Late Bronze Age.

The Alps are of course a stunning natural landscape. However, we should not forget it has been heavily shaped by human activity during the past ten thousand years. And this process continues to this day. The impact of our activity in the Alps, whether in the shape of tourism, mining, transport and the changing agricultural practices should not be underestimated. This means we, archaeologists as well as policy makers, should be aware of the threats our living in and enjoyment of the Alps pose to our cultural heritage. These same activities, however, provide many opportunities to discover hitherto unknown archaeology. The word-cloud lists the most prominent categories of threats to archaeology in the alpine regions. (I wrote more about this here and here.)

concept & production by Th. Reitmaier

However, it is not only through this more `passive´ way of discovery that we can increase our knowledge of the cultural history of the Alps. It has been shown that active searching for archaeological remains, through survey work with well aimed research questions and adequate methodology, can be very successful. These surveys can vary between simple field-walking to predictive modelling (put into practise here) and everything in between.

One cannot protect what one does not know. Cantonal Units can therefore not limit themselves to dig known sites that are in danger of being destroyed, but should increase their knowledge of the archaeology in their Canton and actively search for it, whether in the Alps or in the lowlands.

If you are ever in the Alps and find any archaeological finds in the sides of a hiking path, on a ice patch on a pass or anywhere else, please get in touch with the local police or the people in the nearest mountain hut or hotel and they will pass on the information to the archaeological authorities. We need your help and are very interested in hearing from you!

Hafting microliths – from Scandinavian moors to high alpine slopes

Microliths, superstars of the Mesolithic lithic industries in Europe. They come in many shapes and yes even sizes. Somehow we are all captivated by the image of the hunter, stealthily moving through the green undergrowth at the edge of a forest clearing or through a shallow gully in the moors, it seems. It is in one of these moors that the arrow point described by Larsson and Sjöström (2011) was lost. It has long been established that microliths had many uses. Their acting as tips and barbs of arrows was certainly one of these, as this spectacular find from Rönneholms Mosse, southern Sweden shows. Four obliquely retouched triangular microliths attached to the ca. 10cm long hazel wood arrowshaft formed barbs. A fifth microlith was found immediately next to the arrow and seems to have once served as the tip of the arrow. The authors describe it as having an intermediate shape between an triangle and a lanceolate. So, are we in Central Europe solely dependent on Scandinavian finds for our understanding of the use of microliths?

The only other certain Mesolithic arrow point was found in 1951 in Lilla Loshults Mosse, Sweden (Larsson 2009, Malmer 1969). On one of two arrows found here, the tip, a true microlith, and a microblade, acting as a barb, were still attached to the shaft with resin. Two further microblades acted as tip and barb of a second arrow. Interestingly, Larsson (2009) writes that there are good reasons to believe the artefacts were intentionally deposited. At Vinkel and Holmegaard IV, both in Danmark, fragments of arrow shafts have been found (Becker 1945, Troels-Smith 1962).

arrowheads from Lilla Loshults Mosse, Sweden. Malmer 1969

Most often, though, we have to use less direct evidence and methods to establish the actual uses of microliths and stone tools in general. Occasionally artefacts are found within the skeleton of a hunted animal, such as the shaft fragment and 15 microliths/lanceolates with an aurochs skeleton at Prejelrup, Denmark (Aaris-Sorensen and Brinch-Petersen 1986). Or they are found in direct association with other archaeological evidence, which might indicate their use. Last but not least there’s the fantastic science of microscopic use wear analysis.

I know of two lithic artefacts with the remains of adhesive still attached to them found in the (southern) Central Alps.

Microfauna, archaeobotanical macro remains as well as flint artefacts and worked and un-worked bones that might have been missed on site, are retrieved by slow and concentrated sorting of the sieving residues.

échafaudage. To aid excavation, the site is caged in by scaffolding. It seems to create a distance between the twenty first century archaeologists and the site. It allows us to move around the site. However, only the excavators actually enter the site and even they do so while moving and sitting on boards suspended above the ground. So, for them the scaffolding not only separates the site from its surrounding but also separates them from the site, the archaeology. It seems a bit odd, as excavating is such a tactile activity, always in touch with the dirt and the archaeological remains.

These days the site overlooks a floodplain. The Sarine river flows perhaps 120m from the rock shelter. During the Early Atlantic it would have lain directly below the abri, perhaps also separating it, in a sense, from the outside world. August 2011

Besides, from August 20th our fieldwork in the Fimbertal, Jamtal and many more high and wild valleys continues. Join our alpine archaeological adventures again on the rückwege-blog

a return to the Jura: expanding horizons

I had not expected such a quick return, but yesterday I was in the Jura mountains again. I visited the excavation of the site of Lutter/St. Joseph. It lies just across the border in France on the very northern edges of the Jura mountain range.

This summer has seen some changes for my phd project. My project will hopefully soon be accompanied by a second phd project. L. Bassin (Université de Neuchtel) will study the lithic technology of the Mesolithic-Neolithic transition in northern pre-alpine central Europe. This means a slight overhaul of my project too. One of the biggest changes is that we are looking for other sites to include in our study. Lutter/St. Joseph is the most likely candidate.

Near Lutter a clift in the northernmost ridge of the Juramountains allows access into

St.Ursanne: middle ages and hazelnuts

There has to be some diversion in the life of a phd student. So on a quiet rainy Sunday a few friends suggested a visit to St. Ursanne, Switzerland. (Thanks for a great day L., Chr. & R.!). I have been living very close to the Jura Mountains for a number of years now, but never actually made it there. It was starting to gain mythical proportions in my mind. So, time for some exploration. The whole day I had a nagging feeling that I should know St. Ursanne, that it was known for something else, besides from being a well preserved town and the medieval monastery.

St. Ursanne, from Kunstführer durch die Schweiz 3 (1982)

St. Ursanne lies in the remote but beautiful valley of the Doubs. You enter the town through one of its 3 towers. The town has bags of charm and it is not surprising that it is rather touristy. At its centre lies the church and monastery of Saint Ursanne. Its predecessor was founded ca. 635 AD over the grave of St. Ursinicus, an irish monk and student and companion of St. Columban. The present church and monastic buildings dates mostly to early 13^th C AD and is stylistically truly on the transition of the romanesque to the gothic. The cloister dates to the 14^th C AD. The southern entrance is one of the best pieces of romanesque sculpture in Switzerland. Beautiful, but a little mad is the baroque choir. In the lapidarium one walks over a glass floor under which lie scores of those fascinating early medieval trapezoid sarcophagi made of the local chalkstone.

Cloister, St. Ursanne

Sometime this week it finally dawned on me: the Abri Les Gripons lies just northwest of St. Ursanne! I cannot blame the others for not knowing of this site. Although all four of us were trained archaeologists, none of the other have much to do with the Mesolithic. But I should have remembered. The site was excavated in 1986 – 1989 (Pousaz 1991; see also Nielsen 2009) and is mostly known for its Early Mesolithic horizon. Burned earth and charcoal indicate hearths. Finds include mostly calcinated bones and flint artefacts.

My interest is in the Late Mesolithic horizon, though.

Microliths, Engadin Valley and a museum visit

The past four wonderful weeks I spend in the Val Tasna, camping at 2200 masl, surveying, documenting and digging sites spread over a number of valleys and dating from the 10^th mill BC to the second half of the 20^th century. (The second half of the campaign starts august 19^th – do contact me if you’d like more info.)

Already in 1976 Clarke suggested that Mesolithic microliths might have been used to process plants material, perhaps as grater boards. Although it is still widely assumed most microliths were used as arrowheads, it has since been established that microliths were used for a variety of functions (e.g. through strong associations with plant remains and use wear analysis). Artefacts like this might show us how.

It is a Tscharesch from the Museum d’Engiadina Bassa, Scuol. It was used for working flax. The metal pins, driven with the blunt side into a decorated wooden board function as a comb which loosen flax fibres. One could just imagine replacing the metal pins with flint Late Mesolithic bladelets or what we often assume to be arrowheads.

The «6. Interregionales Silex Symposium» – an interregional/-national early summer’s evening in Basel

Last Friday, I had the pleasure of taking part in the highly informal „6. Interregionale Silex Symposium” in Basel. The fabulous weather allowed for an early May bbq and beer gathering, followed by a stimulating evening of flinty-talk.

Acheulean Implements, Kent UK

D. Schuhmann (Germany) started us off with some musings on the Yabrudien in Hummal other sites in Syria. H. Flück (Fricktal), really a Romanist, took a brave step standing up in front of a room full of hard-core prehistorians and introduced us to the fabulously beautiful knapping work of the Mayas. M. Bolliger (Fricktal) subsequently read out a highly informative alphabetic list of 1000 interesting rawmaterial sites in Europe. We will never again be lost for ideas on what to do when on holidays!

The break was spent with more interregional international beer (Efes, Kronenbourg and Bittburger; thanks to the little Turkish shop next door’s tendency to promote cosmopolitism) outside again and used for much valueless networking, the most useful kind.

I (Limburg) had the honour to start the second block and gave the audience my take on Kohn & Mithens (Antiquity 1999) so called Sexy Handaxe Theory. D. Brönnimann (Baselländer) then proceeded to succinctly explain us the many things we can not learn from flint thin sections. Dr. R. Jagher (Basel) finished off the evening by giving us a slightly worrying insight into the biology and toxicology of the Tuber silexorum (Common Flint nodule) from a Baseller point of view. After which we just managed to get the last train home (although there are rumours that a few locked themselves in the building and stayed a bit longer.)

Thanks everyone for a good evening!

Digging a multi period site in the southern Swiss Alps

It is a wonderful feeling to see, feel and hear how you scrape free a new layer or feature. It does not matter whether your tool is a shovel or trowel, the tool in your hand moving intuitivelly in the dirt, flicking a stone or taking that little bit more dirt away. Or whether your eyes follow the shovel of a mechanical digger as it tentatively scrapes and collects dirt. The texture, colour and the sound, often even the smell change. The distinctive sound of metal against flint or ceramics. I wrote a while ago that I dug a number of prehistoric sites in the Alps last summer. One was in the Val Forno valley, above Maloja in the southern Swiss Alps.

An amateur archaeologist had found a number of Mesolithic flint artefacts in the eroded sides of a hollowed out single track hiking path (Seifert 2008). Me and four friends spend a lovely week’s `holiday´ digging two test trenches to establish the extend of the site, how much it was threatened by erosion and hikers and to see how much it was still present. We uncovered a number of hearths and have since obtained AMS C14 dates from various hearths and layers, spanning nine millennia[1]. We tried to sieve as much spoil as possible on site, but it was impossible to get through it all, so we carried it down. We dragged roughly 50 bags of 4-9 liter of earth down, helped by some very friendly passing hikers, who volunteered to carry some bags down. (Thank you so much, if you happen to read this!)

Last week we continued the site’s excavation in the labs of the Archäologischer Dienst des Kantons Graubünden (Cantonal Unit of Grison). Bag after bag, context by context, we wet-sieved for finds. Using a column of sieves with decreasing mesh-width, water becomes our tool as we wash the finds from the earth. It is much wetter affair, but we agreed that there is still the wonderful smell of moist earth as soon as you open the bag.

Stampa Maloja, wet sieving and flotation residues

However, it is not just the finds that we look for. Flotation allows the recovery of organic macro remains such as charred seeds, (burned) bone fragments and charcoal. Finds are typically scarce on these alpine sites. Seeds, bone and charcoal can tell us much about vegetation, fauna and climate as well as about the diet of the site’s inhabitants. Charred material and charcoal provide absolute dates through C14-analysis and dendrochronology.

In Val Forno we back filled the trenches and took measures to try to prevent further erosion. In our labs and offices we continue our excavation and hope to find some way (the eternal search for funding) to be able to analyse the finds and organic remains in greater detail.

The Aesthetics of Lithics – Marden Henge and Late Mesolithic Switzerland

I have great respect for the prehistoric flintworkers that produced the extraordinary pieces of craftsmanship that stand out from the usual crowd of artefacts and debitage we archaeologists mostly deal with. However, I do not count myself amongst the lithics fans who can dote on these special artefacts for hours. When I saw the picture of these ripple-flaked oblique arrowheads, though, it struck me how much they differ from the late Mesolithic artefacts from Central Europe that I am working with.

Ripple Flaked Arrowheads, Marden Henge. from Leary etal 2010, PAST 66

Let me introduce the mentioned arrowheads briefly. First, they are stunning and amazing pieces of craftsmanship! They were found during excavations by English Heritage at Marden Henge, southern England. Marden Henge dates to the Late Neolithic, ca. 2500 BC and lies between Avebury and Stonehenge. Leary, Field and Russell (2010) briefly report on the fieldwork in Past 66. The arrowheads came from a trench in which a remarkably well preserved building was discovered. More on Marden Henge and the fieldwork can also be found on these sites: The BBC site shows a short video and The Guardian website has an article and a small interactive feature. Digital Digging made this nice little overlay video.

Back to the lithics. Leary, Field and Russell (2010, p. 16) write:

“Two exquisitely crafted ripple-flaked oblique flint arrowheads were also recovered from this trench, but with broken tips and one missing barb each. However, if an intriguing broken fragment of flint from another part of the site is correctly interpreted, these arrowheads may have once sported grossly elongated barbs on one side. This long and narrow surface-flaked ‘barb’ fragment closely matches the character and width of the stubs on the arrowheads – so much so that it almost refits with one of them. Such an overstated feature places the artefact well beyond the realms of practicality, and must have been the ultimate show-off item. As far as we know, nothing similar exists in Britain – and even the barbs on elaborate continental barbed and tanged arrowheads are small by comparison. We lay a challenge here at the feet of all flint knappers out there to try to recreate a similar arrowhead and barb.”

What struck me was how different they are from the finest, most sophisticated artefacts from the Central European Late Mesolithic. And yes, I do realise artefacts from different periods and different parts of the world are being compared. It is also not my aim to do a typological comparison, but to take a moment to look at some of the wonderful things we – as archaeologists – have the privilige to work with, to contemplate how a skill can be used in such varied ways, producing artefacts withi such different functions and meanings.

To me the small trapezes are the most aesthetically beautiful chipped stone tools from Late Mesolithic Switzerland. These, however, can be assumed to have been practical tools, used and hafted as arrowheads, unlike the “ultimate show-of items from Marden Henge”. And unlike the Marden arrowheads, their beauty lies in their simplicity, their elegance, their practicality. With this technique many highly efficient arrowheads (or other tools) can be produced from relatively small pieces of raw-material (if need be raw-material of lesser quality). They can be routinely made and replaced. There is no reason to suppose they were show-off items, in fact when hafted you would hardly have seen much of them.

That almost seems to be a shame with e.g. trapezes like this one, made of rock crystal (from a site in the Central Swiss Alps). Its beauty, it seems, is in the design, and not in an ostentatious display of skill and luxury as in the Marden Henge arrowheads.

Update here!

Digging a Late Mesolithic site in the central swiss Alps

Last Friday a team of archaeologists – amongst which I was lucky to count myself – finished the excavation of a Late Mesolithic site (at ~1475masl) on a future golf course near Andermatt, Canton Uri, Switzerland.

It wasn’t really planned like that, but this summer has seen me digging in the Alps quite a bit, and I will write a little something about that archaeology here, starting with the Andermatt dig:

Archaeologically supervising the construction of a golf resort

view of the site over Hospental and towards the Gotthardpass

The excavation, carried out by ProSpect gmbh and commissioned by the Canton Uri, was the result of a small – much too small for such a huge area, actually – survey project and building brief at the construction site of a golf resort on the valley floor of the Urseren Valley between Andermatt and Hospental. The Canton of Uri, sadly, has not got an archaeological unit, so that there is hardly any archaeological research, ot even rescue excavation done here and the authorities are not familiar with what it means to investigate archaeological sites. So, we got the work rather late and while the building had already started. Because of the nature of the work[i] and the small budget for such a large area, it was also not possible to investigate the whole of the construction site. It was one of the very first rescue archaeology projects carried out in the Canton Uri (Hess et al., 2010). But the canton is trying build up something and has just announced their cooperation with the Kantonsarchäologie Kanton Zug[ii] This announcement and the site got quite a bit of coverage in the local and national media [see links below].

Rescue excavation of a Late Mesolithic site

Open Day / Journées Portes Ouvertes et Découverte d’une fouille préhistorique – Site d’Arconciel/La Souche

From the excavators of Arconciel/La Souche (SAEF):

Dimanche 5 septembre 2010 – Entre 10 et 16 heures.Non loin de l’abbaye d’Hauterive, les falaises de la Sarine abritent un habitat du Mésolithique.

Sis sur le domaine de l’abbaye cistercienne d’Hauterive, l’abri naturel d’Arconciel/La Souche se trouve au cœur des magnifiques gorges de la Sarine, à six kilomètres en amont de la ville de Fribourg. Largement ouvert au sud-ouest, il offre protection, ensoleillement, surface habitable conséquente et accessibilité. A ce titre, il est considéré comme l’un des plus beaux exemples d’habitat de pied de falaise de notre région, un type de sites qui fut particulièrement apprécié par les derniers groupes de chasseurs-cueilleurs du Mésolithique (9700-5000 av. J.-C.).

Estimé dès sa découverte comme l’un des plus hauts lieux de la Préhistoire fribourgeoise du fait de son très bon état de conservation, de sa stratigraphie de plus de trois mètres et de la richesse du matériel mis au jour (près de 15 000 artefacts en roches siliceuses, éléments de parures et plus de 150 000 restes fauniques), mais menacé par l’érosion, l’abri d’Arconciel/La Souche fait l’objet depuis 2003 d’une fouille de sauvetage qui sert également de chantier-école à plusieurs Universités.

Palaeolithic and Mesolithic archaeology in Switzerland – where we stand now

As usual, the 2010 Jahrbuch Archäologie Schweiz vol. 93 includes a list of newly discovered and excavated sites. It is no surprise that the number of Palaeolithic and Mesolithic sites discovered or investigated in 2009 is relatively low in comparison to the number of sites from most later prehistoric, roman and medieval periods. The figure below comes from Siegmund’s 2008 publication in the Jahrbuch der Archäologie Schweiz 2008, vol. 91.

Siegmund 2008 Abb. 9, p. 95. Do not be confused by the typos in the Roman and Medieval numbers: the correct ones are 1630 & 1288.

It clearly shows the chronological distribution of the newly recorded or excavated sites in Switzerland during the period 1987 – 2006. It is also noted by Siegmund, that especially concerning the Mesolithic, Germany and France show even worse records (although for the alpine areas this might not been true; see below). Also, about a third of the Mesolithic sites mentioned in the above table are recorded in only one Canton: Fribourg.

Below the numbers of Palaeolithic and Mesolithic sites, and as a comparison the Bronze Age sites, recorded in 2008 & 2009. It shows ten sites mentioned in 2008 of which five were new discoveries and nine sites mentioned in 2009 of which four were new discoveries, against seventeen and forty-three sites dating to the Bronze Age.

Radiolarite and spring in the Fribourger Prealps

A number of raw materials were used for the production of chipped stone artefacts at the site of Arconciel/La Souche, Kt. Fribourg, Switzerland. Some of you might already know that I am doing a use wear analysis of the finds from the Late and Final Mesolithic abri for my PhD.

Of course, I am curious to see these places and the sources of the raw material of the archaeological artefacts. And it is spring! Here on the Swiss plateau the snow is gone, and in the Alps much has already melted as well. So, Regula and I set out on an expedition to go and find the radiolarite outcrops in the Fribourger Prealps on the Brendelspitz. As guides we had the article by Braillard etal 2003 and the great little book Geologischer Pfad Gastlosen by Braillard and Rebetez (2010) (thank you Luc!).  What these, sadly, did not tell us, was that we underestimated Lady Winter’s resilience and had to fight through leg-deep snow at times. And no, we did not bring snowshoes… By then, we were too foolhardy and just had to get up there!

The main raw materials used at the site during the Mesolithic are “Ölquartzite”, radiolarite and silex (Braillard, Menoud et al. 2003; Mauvilly 2005; Mauvilly, McCullough et al. 2008). Most of these raw materials are to be found at a not too great distance from the site of Arconciel/La Souche. The closest source would have been the Sarine riverbed. Radiolarite, “Ölquartzite” and some types of silex can be found there. In the Jura Mountains various sources of silex are known. Sources of “Olquatzite” and radiolarite are known in the Fribourger Prealps, the range of middle high Alpine mountains in the southern parts of the canton, and in the neighbouring areas of the Bernese Oberland[1]. But I will focuss only on the radiolarite in this post.

Groupe de Travail sur le Mésolithique

Michel Mauvilly of the SAEF has initiated the formation of a «Groupe de Travail» for researches in the Mesolithic in Switzerland and surrounding regions. A first meeting is planned for the end of March or April.

Below the announcement in French and German.

Création d’un Groupe de Travail concernant les recherches sur le Mésolithique en Suisse et les régions limitrophes

Afin de promouvoir le Mésolithique en Suisse et de créer une meilleure synergie entre les différents acteurs de la recherche travaillant sur cette période et de la stimuler, nous proposons de fonder un groupe de travail. En effet, ces dernières  années, plusieurs fouilles importantes, réalisées dans plusieurs cantons, ont confirmé le très grand potentiel de notre territoire dans ce domaine.

Le groupe de travail est ouvert à toutes les personnes, professionnelles de l’archéologie ou non, qui sont intéressées par les recherches concernant cette période.

Nous proposons donc d’organiser une première séance visant à définir le cadre, les modalités et les attentes des différents acteurs potentiels.

Plusieurs dates sont d’ores et déjà sélectionnées pour cette séance entre mi mars et  mi avril 2010 que nous proposons d’organiser à Fribourg.

Bildung einer Arbeitsgruppe zur Erforschung des Mesolithikums in der Schweiz und in den angrenzenden Regionen

Um die Erforschung des Mesolithikums in der Schweiz voranzutreiben und die Zusammenarbeit von verschiedenen, in dieser Periode tätigen Forschern zu fördern, möchten wir gerne eine Arbeitsgruppe ins Leben rufen. Gerade in den letzten Jahren haben mehrere bedeutende Ausgrabungen in verschiedenen Kantonen das enorme Potential in diesem Forschungsgebiet aufgezeigt.

Die Arbeitsgruppe steht allen an dieser Periode interessierten Personen offen, seien es professionelle Archäologen oder nicht.

Um den Rahmen und die Modalitäten dieser Arbeitsgruppe zu definieren und die Erwartungen der potentiellen Mitglieder zu sondieren, möchten wir eine erste Sitzung einberufen.

Für diese Sitzung können wir mehrere Daten zwischen Mitte März und Mitte April 2010 vorschlagen.

Interested? Get in touch with the M. Mauvilly at the SAEF (saef[at]fr.ch) or leave a comment and I’ll get back to you with further details.

E. Nielsen & Wauwillermoos @ Berner Zirkel für Ur- und Frühgeschichte

The Season starts again for the Berner Zirkel für Ur- und Frühgeschichte. And it starts well! Ebbe Nielsen (Cantonal Archaeological Unit Luzern, CH), who is undoubtedly one of the Doyen of the Swiss Palaeo-Meso-scene, will inform us on recent work in the Wauwiller Moos. This dried-up lake in central Switzerland is well known for its – partly waterlogged – Neolithic sites. The Egolzwil-sites will be the most famous.

However, also the Mesolithic (e.g. Schötz 7), the Late Upper Palaeolithic (or the ‘Spätpaläolithikum’, as it is also known in German; e.g. Wauwill Sandmat 16 & 25) and even the Magdalenian (e.g. near by at Kottwil) are represented. The region is one of the few Swiss regions of which the Mesolithic and Late Upper Palaeolithic archaeology is quite well studied and known. This is mainly due to many years of the work by Nielsen and a group of amateur archaeologists.

Interesting is also Nielsen’s corporation with archaeobotanists such as W. Tinner (University of Bern). One of the interesting aspects of this is that it ties in well with the current debate about the occurrence of archaeobotanical evidence for domesticated cereals in central Europe.

It promises to be an interesting evening, so pop-by if you’re around!

AG Mesolithikum, Luzern, CH, 2009

From April 3rd to 5th, the ‘AG Mesolithikum’ 2009 took place in Lucerne, Switzerland. The AG Mesolithikum is really a  group of mostly German Meso-researchers who meet once a year to informally exchange ideas and present their recent work. This year it travelled beyond its German homeland and the meeting was organised by Ebbe Nielsen, of the Kantonsarchäologie Luzern, Switzerland (Cantonal Archaeological Unit of Lucerne).

The Saturday was started with a short but enlightening introduction into the organisation and work of the Swiss Cantonal Archaeological Units, with special emphasis on Lucerne, by Head of Unit Jürg Manser. Willy Tinner followed by discussing the arguments for and against off-site palynological evidence for early cereal cultivation in the Alpine region. Although what he presented was not hugely different from the publication of Tinner etal 2007, it was interesting to hear Willy put forward the arguments in person and to be able to discuss them with him. He made clear that the evidence he put forward was not conclusive, but there is a large chance that Pre-Neolithic populations opened up the forest, especially around lakes and moors, and that around 6500 cal BC an increase in the presence of cerealia type pollen and adventives and apophytes can be observed in many cores. It also once again showed how fantastic the preservation of palynological evidence is in the (circum) alpine lakes.

Jehanne Affolter told us about her methodology for interpreting data on flint raw-material distribution in the circum alpine region. It was brought to the point how limiting the small number of known sites (esp. those well dated and with raw-material data) still is.

Claus-Joachim Kind and Dorothée Drucker presented fragments of 2 reindeer metatarsus from the Holocene site of Siebenlinden II, sth. Germany. Comparative isotope research indicates it would have lived in the same wooded and temperate environment as the roe deer and red deer from the site. D. Drucker next presented how isotope 13C & 15N research could possibly be used to reconstruct the Mesolithic human diet and environment. It seems to me, though, that the few known Mesolithic skeletons from Europe don’t allow for a sufficiently fine resolution yet.

Birgit Gehlen (Blätterhöhle, Hagen, GER), Michael Baales & Ingrid Koch (Kreuztal-Buschhütten & Netphen, GER) and Harald Lübke (waterlogged sites on Rügen, GER) presented new fieldwork in Germany. And Thomas Doppler presented the methodologies used on site by the University of Basel at Lutter, Abri St. Joseph (FR) and Arconciel/La Souche (CH) for recovering organic remains.

Erik Brinch Petersen, the only Danish participant, talked with great enthusiasm about – and showed us many photos of – beautiful decorated amber hangers known from the Danish Mesolithic. On Sunday Michel Mauvilly summarised the surveying work he and his colleagues in Ct. Fribourg (CH) have done. They already located a large number of find-spots in many of the (pre-) Alpine parts of the Canton (e.g. in the Petit Mont, Grand Mont and Oeschels valleys) and their distribution maps show clearly that blank spots on the map are largely the result of research biases. Their search for flint and other stone sources show interesting results as well, esp. when integrated with their survey and on-site work. This also suggests that the lack of knowledge we have of the prehistory of other Alpine regions is largely due to research biases; an observation that is supported by a number of other recent survey projects in Switzerland. But I’ll have to write some more about that in the future.

Thomas Richter (presenting fieldwork at Germering-Nebel (Bayern, GER) and Ebbe Nielsen finished off this part of the conference. Ebbe briefly introduced a site at the shores of the Soppensee (CH), where Late Palaeolithic and Early Mesolithic finds have been made. The Sunday then continued with a tour of the Soppensee and the Wauwilermoos near Lucerne, with its many famous Late Palaeolithic, Mesolithic (e.g. Schötz 7) and Neolithic (e.g. Egolzwil) sites.

Thanks to the organisers at the Kantonsarchäologie Luzern and the participants and especially to Ebbe Nielsen for a few pleasant days in Lucerne.
