Filling some gaps – Recent research into the Mesolithic in the Swiss Alps

It was a scorching hot day in June 2014 in the Italian Dolomites. Now it is Febuary 2016. It is cold and dark out and I can’t wait to get on skis again. Still, it is a good day to think back on that hot June day when Thomas Reitmaier and I presented the results of a decade or so of Mesolithic research in the Alps of south eastern and central Switzerland at the MesoLife conference in Selva di Cadore. It is now available online!

Now you might think, is there any evidence for Mesolithic hunter-fisher-gatherers in the inhospitable high Alps? Well, yes there is. Up to 2007 hardly a handful of surface and loose finds were known. But many hours of dedicated fieldwork by many people have resulted in quite some new information. Thomas and I have tried to pull it all together and write it up. We were not only able to give a good impression of what we know of Mesolithic life in this part of the Alps, but also of what we do not yet know and what is to be done about that!

We are very excited that the corrected proof of the article is now available online as a preprint. So, get in your lazy chair in your snug warm room with a hot bevvy or a beer, look out on the wintery world outside and read all about the marvelous lives of people in the Alps 11’000 – 7’500 years ago. As you do, please also spare a thought for the archaeologists who spend days in rain, fog, sunshine and snow, with or without us, plodding across alpine meadows, climbing obscure passes and help dig innumerable – often empty – test-trenches.

ABSTRACT
Until 2007 only a handful of surface finds dating to between the end of the LGM and the Middle Neolithic were known in the alpine regions of central and south-eastern Switzerland. A number of recent rescue excavations, research projects and single finds have now shown the presence of people at high altitude in these parts of the Alps from the 9th millennium cal BC onwards. Both open-air sites and rock shelters are represented. Many sites lie above the valley floor, in the upper subalpine or alpine zones, and on routes to minor as well as major passes. Together with new palaeoenvironmental data, these archaeological finds allow us first insights into the nature of interaction of Mesolithic people in the south-eastern Swiss Alps with their social and natural environment, as well as their relationship with regions further afield. Furthermore, the finds allow us to start thinking about future research into the early prehistory of the south-eastern Swiss Alps.

I am sorry about the pay wall (but, pssst, check the publications page …).
And when this is not enough entertainment, look for the other preprints of paper on the Mesolithic of the Alps that resulted from MesoLife conference. Many thanks to the editors of Quaternary International and the MesoLife guest-editors for enabling us to publish this here!

Glaciers, forests and prehistory between Andermatt and Hospental

«Gletscher, Wald und Steinzeitmenschen im Urschnertal»

English text below.

Sechs Jahre ist es schon her, dass ich an den archäologischen Prospektionen und Ausgrabungen im Urserntal, zwischen Andermatt und Hospental, teilnahm. Die Funde, welche v. A. aus der Römerzeit, dem Mittelalter sowie aus der Bronzezeit und dem Mesolithikum stammen, wurden vor einigen Jahren ausgewertet und publiziert. Jetzt sind diese archäologischen Funde mit der faszinierenden Wald- und Gletschergeschichte zusammen geführt worden und in einer schönen Sonderausstellung im Talmuseum Urserntal in Andermatt zu sehen.
Neben vielen Bilder, die die Wald-, Gletscher- und Kulturgeschichte illustrieren und einem eindrücklichen Tonbildschau sind viele originale Objekte ausgestellt. So gibt es erstaunlich gut erhaltene und bis zu 8000 Jahre alte fossile Baustämmen zu bestaunen. Sie sind instrumental für das Verständnis des Urserntals so wie wir es heute kennen. Zu guter Letzt ist auch eine schöne Auswahl von archäologischen Funden zu sehen, die etwa 7000 Jahre Menschheitsgeschichte im Urserental widerspiegeln.
Letzten Freitag fand die Vernissage statt, verbunden mit einem erfreulichen Wiedersehen mit alten Kollegen. Die Ausstellung ist noch bis 8. Okt. 2016 zu sehen. Die Öffnungszeiten (Mi-So 16-18:00) erlauben den Besuch nach einen schönen Tag im Schnee oder einer Wanderung im Gotthardgebiet.

Fosil woods in the exhibition “Gletscher, Wald und Steinzeitmenschen im Urscherntal” Talmuseum Urserntal, Andermatt.

It has already been six years since I took part in the archaeological survey and excavations between Andermatt and in Hospental in the Urserntal. Finds dating to roman times, the Middle Ages as well as the Bronze Age and Mesolithic, have been analysed and published some years ago. Now, these finds have been combined with the evidence for glacial- and forest histories and have been made into a special exhibition at the Talmuseum Urserntal in Andermatt.
A great number of visuals and an impressive slide/audio-show illustrate the natural and cultural history of the valley. But many original objects can be seen as well. Amazingly well preserved fossil trees dating up to 8000 years back are essential in explaining the glacial and forest histories of the Ursern valley. The valley’s 7000 year long cultural history is shown through archaeological finds spanning this long period.
Friday, the exhibition was officially opened. It is well worth a visit and for many of us it was a good opportunity to meet up with old colleagues again. The exhibition will be open until Oct. 8th 2016. And the best thing is: the opening times (16-18:00 Wed. – Sun.) mean that it is perfect for a visit after a day on the slopes or after a good hike.

Prehistoric rock crystal extraction in the Alps

I have written about the most famous rock crystal find from the Swiss Alps, the Planggenstock Treasure and the use of rock crystal through the millennia before. We know where the Planggenstock Treasure and other recent finds were originally found. Indeed, often we can show historic mining to have taken place in various clefts, there might even be historical written sources.

Prehistoric rock crystal mining sites in the Alps are rare, though. That is mainly because they were also exploited in historic times and this more recent activity has destroyed evidence of earlier, prehistoric mining. At the Riepenkar cleft, situated at 2800masl in the Zillertaler Alps, in Tirol, Austria Leitner and Bachnetzter are able to separate prehistoric artefacts from younger mining debris through painstaking sieving and selecting. They date these artefacts typologically to the Mesolithic and Neolithic (Leitner, 2013; Leitner and Bachnetzer, 2011). Although I realise the work is continuing, I would have liked a bit more detail about how they come to this date. In Switzerland such extraction sites with evidence of prehistoric mining are, as far as I know, unknown. Rock crystal artefacts, however, are far from seldom in Switzerland

Attinghausen-Geissrüggen, the media and the battle over the oldest Swiss Alp Hut

So often it is the superlatives, the oldest, the biggest, the first that make it into the media. That is what happened with the site of Attinghausen-Geissrüggen in the Canton Uri, “the oldest Alp Hut in Switzerland”, or at least Central Switzerland. (See hyperlinks in the text.) Regular visitors to Hazelnut Relations will know that in 2010 I was involved in compiling the archaeological site inventory of the Canton Uri and during that same summer was part of the team surveying and excavating the area between Andermatt and Hospental ahead of the building of a golf course. Some weeks ago now, I helped some colleagues dig an alpine site in Canton Uri for a few days. And I actually got to wield my mighty trowel! Even though I thought I would not really get to dig at all this summer.

The site my colleagues were excavating is one of over 500 alpine ruins documented during survey work by Marion Sauter and Walter Imhof since 2009. Together with a small team around Urs Leuzinger, they spend a good week excavating the remains of a building, tentatively dated to the 7th – 5th C. BC. More charcoal samples for radiocarbon dating from good contexts will provide more secure dating. Sadly, but not uncommon for such alpine sites, no finds were made within the building’s outline. A structure in Val Fenga, in the Silvretta (in the excavation of which I was also involved), was dated by associated finds and radiocarbon dating to the 6 – 7th C. BC. So, whichever one turns out to be older, it is interesting to see that the evidence for the prehistoric use of the Swiss Alps is increasing.

The site of Attinghausen-Geissrüggen is situated above the bushes on the flank of the ridge.

The Attinghausen structure is situated on the present day route to the Surenenpass. Its function remains unknown, but the media (tv item) has endorsed it as (one of two?) the oldest Alp hut of Switzerland. No evidence for prehistoric alpine transhumance economies in Switzerland was known until the investigation of the structures in Attinghausen and the Val Fenga, but with the investigation of these and further sites, esp. in the Silvretta, we are gaining a much better understanding of the prehistory of trancehumance in Switzerland. First results from pollen cores, taken in moors near Geissrüggen also seem to point in this direction. However, some function related to traffic across the Surenenpass, as is known from historic periods, would also be a possible interpretation. One old and three new surface finds show the pass was used during late prehistoric and Roman times. Interestingly, to this day a chapel stands near where some of these were found.

As the Canton of Uri still has no archaeological service and archaeology still lives a quiet and largely undiscovered and unloved life there, the almost exaggerated media attention can only be seen as a good thing. And that the people of Uri are interested in their archaeological heritage is clearly shown by 150-200 people that visited the excavation over the weekend. Considering that they had to walk up 500 height meters, I’d say that that is a good show up. Thanks to all those visitors and to M. Sauter and W. Imhof for their survey work!

It is hoped to continue the fieldwork 2014. The results of the 2013 excavation will probably be published in the Jahrbuch Archäologie Schweiz 2014.
On November 6th 2013 (18:15), the excavators will talk about thier work at the Abt. UFG at the Universität Zürich. The talk is open to everyone.

Hospental-Moos and the beauty of rock crystal

These artefacts can have something of an old-fashioned beauty, a tactile and organic beauty. There is the smoothness of the slightly undulating percussion ripples on the ventral face. The distal ends are often thin and even and clean-cut, whereas the sides can appear serrated. Where it was severed from the crystal the surface often has a slight oily shine. The opposite side, the dorsal surface, is quite the opposite of organic. It is flat, geometric, sometimes it seems as if it was build up of the thinnest of sheets of crystal. Its mass is fascinatingly transparent. But unlike glass, there are often impurities and ‘healed’ cracks that have grown back together and perhaps the fascination lies in the fact that these impurities and the structure of the opposite outside surface are so very visible.

Merovingian grave ensemble (Grave 413). Rijksmuseum voor Oudheden

The Naturhistorisches Museum in Berne exhibits an amazing array of crystals of all shapes, colours and sizes. The largest of these is the so-called Planggenstock treasure which was found in the crystalline mountains of the Canton of Uri, Switzerland. To this day ‘Strahler’, or ‘Strahlner’, search for rock crystal in the extension clefts of the Central Swiss Alps. An aquarelle from 1868 shows men on a glacier, against a steep rock face, wearing hats and heavy boots, busy with ropes and sledges and carrying racks as they mine the smokey quartz near the Tiefengletscher. The past few centuries most large crystal finds like these have ended up in museums and collections. And in a way the crystal bead from a Merovingian grave from Rhenen, the Netherlands is also part of a collection. A small private collection of beautiful, precious beads made of glass, amber and rock crystal. Later, during the Late Middle Ages and Early Modern times, rock crystal was often cut into reliquaries and splendid bowls, drinking vessels and carafes. Swiss rock crystal was valued by stone cutters, for example in Milan, for its purity and clarity.

Unterseen III: Day of archaeology – a day in Swiss rescue archaeology

A bit late, but here it is, my contribution to the Day of Archaeology! Over 700 archaeologists worldwide show us how diverse our archaeological days are. It is also well worth to have a look at some of the many other entries.

A fantastic achievement of the organisers!

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.

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!

The test-trenching at Bregalia, Val Forno, Plan Canin will be published in the Jahrbuch Archäologie Schweiz 2012:

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].
