About this map

Katmai National Monument dominates the lower half of this landscape, its northern boundary delineated as it stood in the early 1950s. The terrain is defined by dramatic elevation changes rising from the shores of Idavain Lake and Lake Coville toward the prominent peak of Sugarloaf Mountain. This survey was compiled using aerial photography from 1951, capturing a moment when the region remained largely undeveloped and accessible primarily by its water systems.

Water serves as the primary geographic marker here, with the Alagnak River flowing through the northern section and American Creek draining into the lakes in the east. The map provides a detailed study of the glaciated topography and drainage patterns within the monument and its immediate surroundings, illustrating the complex network of unnamed streams and ponds that feed into the larger river systems of the Alaska Peninsula.
