1951 Map of Mount Katmai B-3

About this map

Katmai National Monument defines this glaciated landscape in the early 1950s, centered on the high volcanic peaks of the Aleutian Range. The map captures the dramatic geography of Mt Katmai and its central Crater Lake, along with the surrounding summits of Snowy Mountain and Noisy Mountain. The terrain is marked by extensive glacial features, with numerous Crevasses indicated across the ice fields. This 1951 survey provides a primary record of the drainage patterns for the Rainbow River and Ikagluik Creek before subsequent decades of volcanic and seismic activity further altered the region. The map reflects a period when topographic data was derived from 1955 multiplex methods and 1951 aerial photography, offering a baseline for studying the shifting ice and water of this protected wilderness.
