The glaciers are dynamic resources acting as natural reservoirs for supply of water to major river systems in Northern India with great potential of hydroelectric power generation. These Glaciers  play a significant role in the dynamics of the Indian monsoon, radiation balance due to snow/ice cover providing feedback mechanisms for advection water vapors from the surrounding oceans and for the very maintenance of seasonal cycles of the monsoon. Some glaciers are considered holy and sacred and others are visited for their sheer beauty and serenity.
MAIN GLACIERS
