About this map

Lake Clark National Park forms the heart of this landscape, where high-altitude glacial runoff feeds into a network of significant waterways. The centerpiece is Kenibuna Lake, a large body of water that acts as a hydrologic hub for the surrounding peaks. This area is defined by the massive Shamrock Glacier to the east, which feeds the small Shamrock Lake and contributes to the flow of the Chukachatna River. The map illustrates a complex drainage system where the Chilligan River flows from the north and the Ivitna River and Neacola River carve through the southern reaches of the quadrangle. The lack of roads or permanent structures underscores the wilderness character of the Kenai Peninsula in the early 21st century, revealing a terrain shaped almost entirely by ice and moving water.
