The Teton Glacier

More than any other erosional force, great Ice Age Glaciers sculpted this mountain skyline.  Today, a dozen glaciers flow from the

cirques cut by Ice Age giants.  Teton Glacier, the largest in the park, lies below and northeast of the Grand Teton.

 

Teton Glacier acts like a huge conveyer belt.  Below the glacier, note the terminal moraine, a wall of rock of all sizes transported

by moving ice and deposited at the edge of Teton Glacier's melting snout.

 

For a glacier to remain a constant size, snowfall at the top must equal melting at the bottom.  More snowfall causes a glacier to 

advance, meaning to grow larger.  Less snowfall means retreat.  At any size, to be called a glacier, snowfall compacted into ice

must flow under the pull of gravity.

 

Teton Glacier flows at an average rate of 30 feet per year.
