Glacial rock.

The turquoise lakes are fed by rivers where large, active glaciers are pushing through rocky valleys upstream. The glaciers function like bulldozers, grinding away and pulverizing rocks along valley floors and walls. The process produces a fine-grained powder of silt and clay— glacial flour —that is picked up by meltwater streams.Try these rock and mineral activities for kids and learn more about all sorts of rocks.

A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement.
