Caucasus leads the great interest of scientists with its theoretical and practical point of view, because it is located between the Alps and mountainous systems of Asia, furthermore, in recent years substantial differences between glaciers regime and dynamic of marine and continental regions are revealed, which increases attention to Caucasus so the quantitative data obtained there is important not only regional but also a continental scale. Modern glaciers in Georgia are concentrated in Enguri, Rioni, Kodori and Tergi River basins. Main accumulation zones are related to the watershed of the Caucasus and Kazbegi massive. Also, accumulation zones are on the other ridges of Caucasus. 637 glaciers are presented in Georgia nowadays with an area of 355.80 km2. We used catalogue and maps of glaciers crated by Podozerskiy in 1911 in this research. Although in some cases there are mistakes in visualization of areas and amount of glaciers, but to get information about glaciers Condition at that time. Also we used 1:25000 and 1:50000 scale military topographic maps created by department of geodesy and cartography in the former Soviet Union, where glaciers, ice tongue and equilibrium line on the southern slope of Caucasus are shown in detail. Also we used remote sensing which is an ideal tool for increasing the number of monitored glaciers at the global scale, especially in remote or politically sensitive areas. It has the added advantage of allowing a single user to determine changes in glacier surface characteristics over very large areas (thousands of km2), and is extremely rapid when compared to field investigation. Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) are widely recognized as highly valuable for glacier mapping.
