arconciel/la souche and the high and wild

tamisage. 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. All the earth removed from site is wet sieved by the Sarine river near the site of Arconciel/La Souche. August 2011

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, 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!

various types of radiolarite, from Braillard etal 2003

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.
