About this map

Susitna River and its intricate drainage network define this interior Alaskan landscape as it was documented in the early 1950s. The geography is characterized by high alpine basins and significant water bodies like Butte Lake and the smaller Snodgrass Lake. Transportation in this era was anchored by the Denali Highway, which cuts across the northern terrain, providing access to this high-country region of the Matanuska-Susitna Borough.

Detailed hydrography includes numerous mountain-fed streams such as Wickersham Creek, Monahan Creek, and Gold Creek, which flow toward the primary river valley. Surveyors from the Geological Survey established several vertical angle benchmark stations, including VABM Nadiwen 5187 and VABM Way 5896, to triangulate this complex topography. A Gaging Sta on the Susitna indicates the importance of monitoring these glacial and snow-fed water systems during this period of mid-century infrastructure expansion.
