Summary

The rich lithic assemblages from the sites Arconciel/La Souche and Onnens/Praz Berthoud provide new insights into the end of the Mesolithic in western Switzerland. The continuous stratigra-phic sequence at the rock-shelter of Arconciel/La Souche (canton of Fribourg) was excavated between 2003-2012. It evidences the repeated occupation of the site between 7100-4800 BC. The numerous projectile points found here show the typological development of this artefact category throughout its occupation. This development is characterised by the appearance of Late Mesolithic blade and trapeze industries just before the middle of the 7th Millennium BC and a continuing tradition of production into the 5th Millennium BC. Macro- and microscopic use wear analysis of a sample of artefacts allows the discussion of the function of artefacts which are habitually called projectile points. These analyses indicate multiple uses of the artefacts throughout the site’s occupation and show how those artefacts used as projectile points were probably hafted. Excavated between 1997-2004, open-air site Onnens/Praz-Berthoud (canton of Vaud) is another rare example of a recently excavated site dating to the end of the Mesolithic on the Plateau Suisse. In addition to a comparable corpus of Late Mesolithic projectile points, an assemblage of Early Neolithic, 5th Millennium lithic artefacts extends the chronological range offered by Arconciel/La Souche. Although there are small differences between the projectile point assemblages from the two studied sites, there are many parallels as well. This is especially true for the symmetric and rectangularly shaped trapezes and some of the so-called “evolved” points. A diversification of shapes can be observed towards the end of the Mesolithic. This diversification is accompanied by an increasingly asymmetric trapezes and the appearance of small, asymmetric points with concave bases, called “evolved” points or “fléchettes”. With time these small points show ever increasing inverse and invasive retouch, slowly developing the characteristics of Early Neolithic points. The comparative study of two assemblages of projectile points provides new insights into the typological characteristics and their developments throughout the End of Mesolithic and the beginning of the Neolithic north of the Alps. This study increases our knowledges of the Late Mesolithic of the Swiss Plateau, while the archaeology of the following period, esp. that between 4800 and 4500 BC remains difficult to grasp here. Little comparative material is momentarily available for the rare material from this period from Onnens/Praz Berthoud.

Résumé

Avec chacun de riches séries lithiques, les deux sites d’Arconciel/La Souche et d’Onnens/Praz Berthoud viennent compléter nos connaissances de la fin du Mésolithique en Suisse occidentale. L’abri sous roche d’Arconciel/La Souche (canton de Fribourg) a comme principale caractéristique une stratigraphie conséquente, avec des phases d’occupation qui se succèdent chronologiquement presque sans interruption de 7100 à 4800 av. J.-C. Il livre également une série importante d’armatures dont l’évolution typologique jalonne le remplissage de l’abri. En plus d’un corpus comparable du second Mésolithique, le site de plein air d’Onnens/Praz Berthoud (canton de Vaud) vient quant à lui apporter un assemblage de pièces qui sont datées dans la continuité au cours des quelques siècles postérieurs à 4800 av. J.-C. L’observation des séries de ces deux sites apporte des élé-ents de caractérisation typologique pour la fin du Mésolithique au nord des Alpes. En plus de cette approche typologique, la fonction de ces pièces définies comme armatures est également questionnée avec l’analyse tracéologique de quelques artefacts d’Arconciel/La Souche. Les résultats de ces observations conjointes mettent en évidence la diversité des armatures de la fin du Mésolithique avec une évolution des trapèzes qui deviennent de plus en plus asymétriques, parallèlement à l’apparition de petites pointes dites « évoluées » (fléchettes, pointes asymétriques à base concave) tendant vers des pièces davantage recouvertes de retouches rasantes, jusqu’à celles caractéristiques … (auch auf Deutsch unten)

The alpine Mesolithic and the scrapers from Arconciel/La Souche. Oh, and much much more!

Way back in 2014 Laure Bassin and I presented the first results of our Gestures of TransitionsGestures of Transitions project at the MesoLife conference in Selva di Cadore in the beautiful Dolomites. Now these results have been published in a new volume of Preistoria Alpina. We could increase our results beyond those presented in the poster then and are pleased to be able to show a nice summary of our study of the scrapers from the Late Mesolithic layers at Arconciel/La Souche, Switzerland.

Scrapers are special at this site. Not only are many extremely small, an extraordinary large proportion of tools found at Arconciel/La Souche, over 50% of tools, were scrapers. So, curious about what we found out about these seemingly so insignificant little tools? You can download the paper here:

Cornelissen, M. and Bassin, L., 2016. Alpine raw materials and the production and use of scrapers at the Swiss Late Mesolithic site of Arconciel/La Souche, Preistoria Alpina 48, pp. 11-19

Abstract

The well stratified rock shelter site of Arconciel/La Souche, Switzerland was repeatedly occupied between 7100 and 4900 cal BC. It lies in the Sarine river valley at the foot of the Prealps. This paper presents the first preliminary results of the study of the scrapers from this site. Of the chipped stone tool categories, scrapers are the most numerous found at Arconciel/La Souche. A combined technological and microscopic use wear study of the scrapers from three assemblages (ensemble

3, 4 and 5) has allowed us to examine the use and production of scrapers as well as how production and use relate to the various raw materials utilised at Arconciel/La Souche. We were able to show that although scraper morphology remained stable over time, there was a significant change in the relationship between raw materials and scraper production as well as the use of scrapers.

This research will be expanded to include other assemblages and chipped stone artefact categories from Arconciel/La Souche, but has already provided important new insights into artefact use-life in the still relatively poorly understood millennium leading up to the end of the Mesolithic on the Swiss Plateau and the nearby Prealps.

But there is even more! Preistoria Alpina has changed its set-up. The journal is now only available online and open-access. All posters from the MesoLife conference were published in this volume and are available! The papers presented one those hot summer days in the Dolomites have recently been published in volume 423 of Quaternary International. (With a little something about recent Mesolithic finds in the Swiss Alps by Thomas Reitmaier and myself.) That makes an amazing total of 48 articles on alpine Mesolithic!

These two volume show how vibrant the research of the Mesolithic in alpine and mountainous enviroments has become of late and will undoubtly be shown to be valuable additions to our knowledge of the Mesolithic in Europe. Hats off to the MesoLife organisers and editors of these two volumes!

The “Gestures of Transition” circus tours Switzerland

It’s been a busy few weeks for Laure, my project partner, and me. We’ve been doing a bit of a tour of Switzerland, presenting and discussing our research. Back in February I did a so-called “lightning talk” (6 min) on Late Mesolithic scrapers at a colloquium for PhD candidates in Archaeology of the Universities of Basel, Berne and Zürich in Basel. It’s an interesting format, forcing you to focus on what is essential in your research. It provides a nice challenge for the speaker in that she/he has to really think about what are the most important points she/he wants to get across to her/his audience and how to do so. As a listener they are pleasant to listen to, as they are meant to have a good narrative, focuss on a single or few main points and leave out lots of secondary material. I think a lot of conferences/round tables etc. would benefit from having at least some presentations being held in some form of short presentation.
Last week, those researchers involved in the post-excavation analyses of Arconciel/La Souche met in Fribourg to share their first results and discuss how to continue. We were able to see a selection of finds, such as the bone and antler tools and Laure showed us briefly how she is dealing with 25,000 lithic artefacts. It’s nice to see, that besides Laure’s and my work on the lithic artefacts, other work is also getting underway. Patricia Vandorpe is studying the archaeobotanical macro-remains. Luc Braillard has been studying the sedimentological thinslides, providing new evidence on sediment ontology in the rock-shelter. And Aurelie Guidez is getting the first interesting results on the faunal remains from the younger occupation at Arconciel/La Souche.

After a fruitful meeting in Zürich on Wednesday with Prof. Ph. Della Casa, project PI and one of my PhD supervisors, Laure and went to present our methodology and first results to her colleagues at the Université de Neuchâtel. I had been to Neuchâtel a few times before, but had always had bad weather. So, not only have I come back from Neuchâtel with happy memories of interesting discussions, but I am also very chuffed to have finally seen the beautiful Lac de Neuchâtel and the view of the Alps from there!

So, thanks to everyone we met, who listened to and discussed with us and for the invitations! But, after meeting so many colleagues all over Switzerland and after all the stimulating discussions, I have to say I am keen to once again get on with my research and get writing again!

Sharing the joy of scrapers

Fribourg near the SAEF

Today I met up with my project partner Laure in Fribourg, to discuss our progress and collect another sample of chipped stone artefacts for use wear analyses. We do not work in the same place and do not see each other every day. So, it is always stimulating and encouraging and fun to meet up and exchange ideas and plans as well as problems and results.

30 000 chipped stone artefacts (8000 – 7500 years old) on a table

At the moment we are both working on the Late Mesolithic scrapers from Arconciel/La Souche, Switzerland. We are working towards a poster for the MesoLife conference this June and it is our aim to look at the relationship between production, use and raw material of the exceptionally many scrapers found at Arconciel/La Souche and how this develops towards the end of the Mesolithic. It was great to see that the method of our combined approaches will, as we hoped and planned, indeed bear fruit and comparing technology and typology with use will bring further insights into Late Mesolithic behaviour just North of the 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

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.

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, with a trusted companion 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!

various types of radiolarite, from Braillard etal 2003

The main raw materials used at the site during the Mesolithic are “Ölquartzite”, radiolarite and flint (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 flint can be found there. In the Jura Mountains further flint sources 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.
