Description

This is part of an effort by the U.S. National Park Service to document glacier change in our glacierized national parks. This 360 degree view from the middle of the Kahiltna Glacier. At these specific coordinates on the glacier, glaciological measurements are made twice a year to track long-term changes. A visit in the spring attempts to capture the maximum accumulation of winter snowfall at the site and another in the fall to measure how much snow and ice has melted over the summer. GPS measurements are made to track changes in surface elevation and movement of a metal stake tracks changes in glacier velocity as well as surface snow and ice melt. Measurements have been made here since 1991.
