The glacial area changes of 173 glaciers in the Andes (15°45'S~17°00'S, 67°15'W~68°30'W), Bolivia were determined using satellite data between 1988 and 2012. Total of glacial areas in 2012 decreases to 78% from 1988. The decrease rate of large-scale glaciers more than 5.0km2 was high. The aim of this paper is to analyze glacier retreating with glacier characteristics, which are area, latitude, longitude, maximum/minimum/average elevation, area-aspect, area-slope, and area-hill shading. The values of glacial area, average elevation, and area-slope are very sensitive to glacier retreating. On the other hand, the value of the area-aspect is not sensitive. In addition, we constructed the estimated formula of glacier retreating volume. This adjusted R-square is 0.693. The total area estimated in 2036 is 170.2 km2 which is the 64% of 1988.
