Tsagaan Agui (White Cave; Цагаан Агуй), located in the Gobi Altai Mountains of southern Mongolia, represents one of the few stratified and well-dated Pleistocene archaeological sites now known in the Gobi Desert. Archaeological studies undertaken at Tsagaan Agui since 1995 have revealed that the cave’s sediments contain cultural remains ranging from the Middle and, possibly, Lower Paleolithic, to the later historic period. Analyses of these deposits suggest environmental conditions favorable for intermittent human occupation existed throughout most of the Pleistocene and early to middle Holocene, the latter likely during periods of larger-scale climatic and environmental degradation.
