1951 Map of Mount Katmai D-2

About this map

Glacial ice and high-altitude basins dominate the interior of this mid-century survey of the Alaska Range. The Kamishak River serves as a primary drainage corridor in the southeast, winding through a broad valley floor toward the coast. Higher in the mountains, the Little Kamishak River cuts through a deep canyon, its course fed by numerous unnamed tributaries and snowfields. The terrain is marked by significant topographical relief, with the Mc Neil River draining the northern slopes and Strike Creek carving a narrow path through the central uplands. This 1951 documentation, based on aerial photographs from the U.S. Army Corps of Engineers, provides a detailed record of the glacial extent and drainage patterns before modern climatic shifts altered the landscape.
