1951 Map of Mt Katmai

USGS Topo · Published 1984

About this map

Mt Katmai and the surrounding volcanic terrain dominate this 1951 survey, which documents a landscape profoundly reshaped by early 20th-century eruptions. The map centers on the Valley of Ten Thousand Smokes, where the drainage of the Lethe River and Knife Creek is shown cutting through deep ash deposits. Geologic landmarks such as the Trident Volcano, Novarupta, and Baked Mtn illustrate the region's active tectonic nature.
