A dominant feature of the 600,000+ acre Kenai Fjords National Park is the Harding Icefield, a 300-square-mile icefield. Exit Glacier gets it name from being an exit from that massive sheet of ice. Exit Glacier is the most accessible of the park's glaciers. We took a 2.6 mile ranger-led trail up to the face of the glacier. Their were many warning signs as you approached the glacier, since glacier ice is unstable, unpredictable and very dangerous.
