The main goal of the TSARP is to reconstruct and examine the nature of the occupation of the area so-called Flint Valley by hunther-gatherers groups in the Late Pleistocene and Early Holocene. The study area is located in the SE part of the Artz Bogd massif (Bogdyn Nuruu, Gobi Altai Mountains), which is the border area between the Shereegeen Gashoon and the Ulan Noor basins. This area has been well described in the literature as Tsakhiurtyn Hondi (ang. Flint Valley), which is an extensive flint outcropping and a cluster of Pleistocene flint workshops. The most significant feature of the landscape, located to the south of Flint Valley are paleolake basins well visible in the area’s topography. More than 120 open-air sites were dicovered during survey carried out on the shores of paleolakes. Moreover, new cave sites was discovered in mountains, located several kilometers from Flint Valley.
