1955 Map of Big Delta A-1

About this map

The South Fork Goodpaster River and its northern tributaries, Serpentine Creek and Divide Creek, define the high-elevation drainage patterns in this mid-1950s interior Alaska survey. This region is characterized by significant topographic relief, where the Volkmar River and Healy River carve distinct valleys through the landscape. The mapping reflects a period of systematic aerial photogrammetry by the Geological Survey, documenting the vast, roadless reaches of the South Boundary Fairbanks Meridian. Insights into the land management of the era are visible through the predetermined, unsurveyed land lines established by the Bureau of Land Management. The map serves as a primary record of the hydrological network before significant modern infrastructure reached these remote basins, highlighting the prominence of Michigan Creek and the intricate river systems that were the primary landmarks for mid-century travelers and surveyors.
