1956 Map of Tanacross C-4

USGS Topo · Published 1964

About this map

West Fork Dennison Fork winds through this interior Alaskan wilderness, as documented during a mid-1950s Geological Survey aerial survey. The landscape is defined by its extensive drainage systems, where high-altitude ridges descend into broad, swampy valleys marked by numerous small ponds and thaw lakes. This specific quadrangle captures a moment before modern infrastructure reached this part of the Copper River Meridian, showing the land as it existed when only the Bureau of Land Management had predetermined unsurveyed land lines. The terrain is a complex network of unnamed peaks and ridges, where the water patterns of the West Fork Dennison Fork provide the primary geographical orientation for the region.
