About this map

Mount Russell dominates the southern portion of this high-altitude landscape, situated along the Matanuska-Susitna Borough line. This 1958 survey captures a frozen wilderness defined by massive ice flows, including the Chedotlothna Glacier, Yentna Glacier, and Lacuna Glacier. The northern reaches of the sheet are protected within Mount McKinley National Park, a region where the South Boundary Fairbanks Meridian marks a critical surveying baseline.

Surface water is primarily represented by the Swift River and the headwaters of the Kuskokwim River, which navigate the steep terrain outside the glacial fields. Map notes indicate that land lines here represent unsurveyed and unmarked locations predetermined by the Bureau of Land Management, reflecting the remote nature of the Alaska Range before modern infrastructure. Numerous Crevasses are mapped across the glaciers, signaling the active and shifting state of the ice during the mid-century.
