About this map

Lake Clark National Park encompasses a significant portion of this high-elevation wilderness, where steep slopes and alpine ridges dominate the landscape. The terrain is defined by extreme relief and complex drainage patterns, with contours rising sharply through the protected park lands. The boundary between Matanuska-Susitna Borough and Kenai Peninsula Borough bisects the region, marking a jurisdictional line through a remote and uninhabited expanse of the Alaskan interior. This 2017 survey by the U.S. Geological Survey illustrates the intersection of these major administrative districts within a landscape characterized by deep valleys and high mountain passes, offering a detailed topographical view of a region defined more by its natural boundaries and federal protections than by human settlement.
