Excavations took place between 3rd – 28th June, the aim being to deepen the excavation in the area of the 2007 campaign. The surface visible at the start of the campaign corresponded to the top of US2 base, constituted by yellowish-brown loess partially disturbed by plant growth, containing a slight charcoal patch, some bones of small carnivores and numerous remains of micro-mammals. Four flint micro-flakes, fragments of mammal bone diaphises and a marmot’s jaw bone came from the lower part of the layer. US2 base also contained ferrous concretions and several clasts. The underlying layer US3a was characterised by altered and rounded limestone clasts in a dark brown clayey-silt matrix. It contained remains of cervids and other ungulates and lithic industry of “Scaglia Rossa” and “Scaglia Variegata” flint (a lamellar core, several blade flakes and abundant debris). The US3b was distinguished by the presence of large boulders which had fallen from the vault and walls of the cave. Below the collapse the sediment became sandy-silt. The upper part of US3b produced only a few bone fragments with a shiny surface (perhaps swallowed and digested by carnivores), bear teeth, fish and bird remains. It also contained some flint micro-flakes, two blade fragments of “Scaglia Rossa” flint (one with a marginal steep retouch). At the base of US3b carnivore and herbivore bones were recovered, some showing man-made marks. Murids were present among the micro-mammals indicating an environment which included undergrowth. The underlying layer US4tI was characterised by a continuous horizon of collapsed stones and boulders, with faunal remains and some flint flakes. At the base of this layer was a horizon containing charcoal of anthropological origin. Flint artefacts made using the Levallois technique, attributable to the Mousterian period, were found situated between two hearths.
