1951 Map of Ugashik D-3

USGS Topo · Published 1975

About this map

Becharof Lake dominates this 1951 aerial study of the Alaska Peninsula, where a complex network of wetlands and tundra ponds defines the shoreline. The mapping reflects a landscape shaped by glacial retreat and hydrological shifts, showing the vast expanse of water that characterizes the region between the North Pacific and the Bering Sea. In the south, the terrain begins to rise toward Upper Ugashik Lake, providing a distinct transition from the low-lying coastal marshes to the elevated interior. A single named triangulation point, VABM 243 Rost, serves as a rare vertical benchmark in an area primarily defined by its horizontal watery expanse. This survey, conducted shortly after the war using photogrammetric methods, captures the intricate and largely uninhabited drainage patterns before modern environmental changes altered these sensitive subarctic ecosystems.
