About this map

The Alaska Peninsula National Wildlife Refuge and Aniakchak National Preserve converge in this high-resolution study of the Aleutian Range. The terrain is defined by dramatic elevation changes and a network of glacial and volcanic drainages, most notably the winding paths of Pumice Cr and Painter Cr. These waterways carve through complex topographic contours, illustrating the raw geological forces at work on the Alaska Peninsula.

While largely devoid of human structures or roads, the map serves as a vital record of federal land boundaries and hydrographic patterns. The proximity of the preserve and refuge highlights the region's significance for conservation and scientific research. Small tributaries like Old Cr feed into larger systems, providing a detailed look at the watershed before it reaches the coastal lowlands. This survey is essential for understanding the remote wilderness character of Lake and Peninsula Borough in the early twenty-first century.
