This paper analyzes archaeological remains from Verkholenskaia Gora in Cis-Baikal and discusses the placement of this culture in the archaeological sequence of the Baikal region. The tools are classified on the basis of manufacturing technique and technological function. The discovery of a bone arrowpoint at this site may increase the antiquity of the bow by several millennia. A comparison of the materials from Verkholenskaia Gora with materials from other regional archaeological assemblages suggests that the site was occupied at the end of the transitional period that extends from the Palaeolithic of the Mal'ta stage to the Neolithic. Verkholenskaia Gora is therefore assigned to the Siberian Mesolithic.
