Kenai Fjords National Park
In Kenai Fjords National Park, over half of the landmass is covered by the enormous Harding Icefield, a thousand-foot block of ice that dates back to the last Ice Age. The Harding spills out in all directions in the form of glaciers. Some stretch northwest into rugged hills of the Kenai Peninsula. Others—five of them, to be exact—reach as far as the sea along the craggy coast of the Gulf of Alaska.
