Tsagaan Agui

Tsagaan Agui, the White Cave, lies in a limestone massif in the Gobi Altai. Crystals of calcium carbonate line its inner chamber, while layers of deposits hold stone tools left by ancient visitors. Jasper outcrops above the entrance supplied material for toolmaking, and flakes scattered around the cave show that stone was worked there. Animal remains found in the cave include horse, gazelle and ostrich.
