Kenai Fjords National Park is not very far from where our home now is. The Harding Icefield's expanse covers over half of the 669,983-acre park and conceals a mountain range under ice several thousand feet thick. Exit Glacier is one of about 40 arms (glaciers) which project off from the Harding Icefields. It is one of the more accessible of all the glaciers for scientists to study environmental factors influencing glacial retreat and advance. From the park's visitor center we hiked over glacial moraines and bedrock to the edge of the glacier. It was awesome to be that close to it and look down into its ice-blue glacial crevasses.
