About this map

The glacial waters of the Hayes Glacier dominate this mid-century view of the Matanuska-Susitna region, feeding into a complex braided drainage system where the Hayes River and Trimble River converge. The landscape is defined by its transition from high ice fields to the lower river basins, where the wide Skwentna River snakes through the northern portion of the quadrangle. Scattered throughout this wilderness are clear landmarks for navigation and survival, including several lakes like Red Lake, Finger Lake, and Red Salmon Lake.

A lone Cabin situated along the riverbank serves as a rare sign of human activity in an area otherwise governed by terrain features such as Porcupine Butte and Dickason Mountain. Surveyed using aerial photographs from 1952 and 1957, the map illustrates the raw hydrography of the Alaskan interior before modern development, capturing the intricate patterns of Old Man Creek and Spring Creek as they negotiate the valley floors.
