1951 Map of Mount Katmai D-5

About this map

American Creek dominates this 1951 aerial survey, winding through a glacial landscape toward the expansive Nonvianuk Lake in the north. The map documents a critical era for the Katmai National Monument, showing its National Monument Boundary cutting across the southern terrain. This region represents the untouched Alaskan interior prior to the major expansions of the park system later in the century. In the southwest, the waters of Lake Coville appear, illustrating the interconnected lake and river systems that define this remote watershed. The survey reflects the early use of photogrammetric mapping in Alaska, capturing precise topographic contours and drainage patterns that were only beginning to be systematically recorded by the Geological Survey during the post-war years.
