Due south of Anchorage, the Kenai peninsula stretches southward, with the Gulf of Alaska on its east and Cook Inlet on its west. Much of the Peninsula is contained within Kenai Fjords National Park. The fjords after which the park was named are long, steep, glacier-carved valleys that are now filled with ocean waters. Glaciers still abound in the region, and the entire range is mantled by an enormous glacial network known as the Harding Icefield. The icefield is 35 miles long and 20 miles wide, and only isolated peaks poke through its surface, including the highest, Truuli Peak (6,612 ft./2,015 m.). Access to the region is from the town of Seward, Alaska.
