Large chunks of ice moving down the slopes, floating downstream in their icy magnificence lead one, not only to marvel at these creations of nature, but also to ponder over their broader function in influencing the existence of life.,, since they are essentially water in frozen form. Spectacular and magnificent, the glaciers have a life and beauty of their own and feed the perennial rivers originating from the Himalayas. They are an integral part ofthe mountain landscape and are found in all parts ofthe world, where the rate of precipitation is greater than the rate of melting of snow, a condition exclusive to mountainous regions. The snow line however depends upon the altitude and the latitude and accordingly varies from 4500 mts. to 5400 mts. in the Himalayas to the sea level in the polar regions. The Himalayan glaciers are called temperate valley type and are much smaller in size as compared to polar glaciers. Glaciers are of special interest to mountaineers as they often provide the easiest approach to a peak.
