Cave Description: The cave has a small entrance. The cave continues in the form of a horizontal winding tunnel about 170 meters long. The floor is covered in a thick layer of cave sediments.
Research Chronicles and Data: This cave was first investigated in 1992 for archaeological and palaeolontological remains. A thin Holocene stratum was noted (stratum 1) with Eneolithic and later pottery, as well as rare faunal remains, like Ovis and Capra. There was a thicker Pleistocene sediment (strata 2-3) with numerous cave bear remains (Ursus spelaeus), less numerous brown bear (urusu arctos) and Alpine marmot (marmot marmot) finds, and , as well as the rare cave lion find (panther leo spelaean).
Layer 1 consists of Holocene humus and rubble with a few were thin greyish colour lines.The layers and lines of the did not revel any traces of charcoal to the excavators. The layer has a thickness of 20-30 cm.
Layer 2 is the first layer of the Pleistocene, with remains of cave bears and the Alpine marmot. The layer consists of sharp-edged rubble and light brown stones. The upper layer was undoubtedly eroded, as evidenced by a lack of sedimentation emptiness between layer 2 and I. The boundary with a layer 3 is blurred.
Layer 3 is different from the surface layer through the colour of the clay, and the curvature of sand and rubble. The layer is a brown colour. The lower layer is darker.
A fragment of the wall of the cave is ornamented, with incised herringbone motif or zig-zag motif. The wall has parallels to Boleráz in Slovakia and late Neolithic northern Italy. In Dolenjska and Bela Krajina, such ornamented ceramics were first encountered, this puts the horizon in the early Eneolithic.
