Photo Friday: Fieldwork on Gulkana Glacier

The U.S. Geological Survey (USGS) has been collecting mass balance data on Gulkana Glacier ever since 1966. Gulkana Glacier is one of USGS’s two “benchmark” glaciers in Alaska, for which it has been patiently gathering data on an annual basis for the last fifty years. The glacier, looming 1300 meters in elevation, is located along the south flank of the eastern Alaska Range.

This Friday, enjoy photos of USGS’s fieldwork on Gulkana, including stunning photos of the glacier itself, the Northern Lights, and a lunar eclipse.
