Tour of Park Geology - Glaciers and Glacial Landforms

Glaciers emblem

Glaciers are important as indicators of climatic change, as objects of beauty, and as sources of water and recreation. Because glaciers store snow and ice during cold seasons and release it as water during hot, dry weather, they are natural and effective regulators of their water supply. Glaciers have covered almost a third of the world's land throughout time. Evidence of past and present glaciation can be found across our national parks.
