Almost all the branches of Geographical science were elucidated in his works: geomorphology, physical geography, paleogeography, karstology and speleology, history of geographical discoveries et al. In his young years he was fond of mountaineering and conquered tens of peaks and high mountain passes.
Scientific activities
He produced over 500 scientific and popular scientific works in Georgian and Russian languages, among then there are 30 monographs and booklets. The results of his numerous research fields - works in the territory of Georgia and other regions of the Caucasus and the Pamirs are given in these works.
