About this map

Mt Deborah and Hess Mountain dominate this section of the Alaska Range, serving as the high anchors for a massive network of moving ice and alpine drainage. The landscape is defined by the convergence of several major ice fields, most notably the Gillam Glacier and the Yanert Glacier, which carve through the high-altitude terrain.

In the southern reaches of the quadrangle, the West Fork and the Susitna Glacier illustrate the headwaters and glacial origins of the region's complex water systems. This 1950s-era topographic survey, based on aerial photography from 1952 and 1956, documents the mid-century extent of these ice masses before late-twentieth-century shifts. The map provides a critical look at an unsurveyed wilderness where land lines remained predetermined by the Bureau of Land Management rather than established by physical markers.
