1951 Map of Mount Katmai C-3

About this map

Katmai National Monument defines the landscape of this 1951 aerial survey, centered on the complex drainage systems of the Savonoski River and Rainbow River. The map documents a volatile geological environment where high-altitude landmarks like VABM 3462 Scrab overlook deep canyons and braided glacial waterways. The confluence of Hardscrabble Creek and Gorge Creek reveals the intense erosion patterns characteristic of this volcanic region, captured here during early federal efforts to delineate monument boundaries. The presence of Falls along unnamed tributaries underscores the steep, unmapped gradients of the interior. This topographic study is a rare primary source for understanding the hydrologic layout of the Alaska Peninsula before modern climate shifts and volcanic activity further altered these river courses.
