1951 Map of Mount Katmai B-3

About this map

Katmai National Monument preserves a dramatic volcanic landscape as it was documented by photogrammetric methods in the early 1950s. The map centers on the high-altitude terrain surrounding Mt Katmai, where the iconic Crater Lake sits within its caldera. This period of documentation shows the extensive glacial presence and the intricate network of crevasses that defined the slopes of Snowy Mountain and Noisy Mountain before decades of further climatic shifts. In the northern reaches, the Rainbow River and Ikaguik Creek drain the high country, cutting through a wilderness devoid of any established roads or trails. The inclusion of survey markers like VABM 3411 Crater reflects the meticulous effort of the Geological Survey to triangulate this complex Alaskan topography.
