The park covers an area of 669,984 acres on the Kenai Peninsula in south-central Alaska, west of the town of Seward. The park contains the Harding Icefield, one of the largest ice fields in the United States, and is named for the numerous fjords carved by glaciers moving down the mountains from the ice field.
