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.
