Stop 6
Isabelle Glacier

Isabelle Glacier is one of the smaller glaciers in the Front Range. Studies have shown that this glacier seems to be in a state of equilibrium with its environment, neither expanding or contracting much over time (Outcault and McPhail, 1965). Movement has taken place, as crevasses are apparent on the surface of the glacier. Crevasses are cracks in the ice created by differential movement or, expansion and contraction taking place within the ice.

Near the edge of the glacier lies a moraine, a typical feature associated with glaciers. Go over and check it out.
