About this map

The Aleutian Range dominates this landscape on the Kenai Peninsula, where high-altitude ice and glacial runoff shape the terrain. A significant portion of this area is protected within Lake Clark National Park, preserving a wilderness defined by its dramatic elevation changes and geological activity. Two major ice bodies, Shamrock Glacier and Tanaina Glacier, are visible in the eastern half of the quadrangle, illustrating the persistent glaciated state of this subarctic region in the early 21st century. The Neacola River flows through the northwestern corner, representing the drainage systems that feed from these mountain ranges into the larger Alaskan watershed. This survey captures a moment in the modern environmental record, showing the exact extent of glacial coverage before seasonal shifts and long-term climatic patterns further alter these massive ice fields.
