1951 Map of Ugashik D-3

About this map

The massive shoreline of Becharof Lake dominates this 1951 aerial study of the Alaska Peninsula, showcasing a landscape defined by expansive wetlands and glacial hydrology. This remote coastal interior, captured by the Geological Survey during a period of intensive post-war topographic mapping, reveals a complex network of marshes and small kettle ponds that fill the lowlands between the larger bodies of water. In the southeastern corner of the quadrangle, the map captures a portion of Upper Ugashik Lake, while the higher ground is marked by survey points such as VABM 243 Rost. The absence of roads or established settlements emphasizes the wilderness character of the Third Judicial Division at mid-century, where topography was recorded using multiplex methods from aerial photography to document the intricate drainage patterns of the tundra.
