1955 Map of Umiat D-1

About this map

The Kachemach River and Miluveach River define this stretch of the Alaskan North Slope during the mid-1950s. This territory is characterized by a dense network of thaw lakes and ponds, showing the intricate hydrology of the permafrost landscape before large-scale industrial development reached the region. The U.S. Army Topographic Command utilized photogrammetric methods from 1955 aerial photography to document these waterways as they meander through the Colville River drainage area. While the terrain lacks established settlements or infrastructure, the map provides an essential record of the pristine Arctic tundra and its drainage patterns, offering a precise view of the hydrological state of the Arctic Coastal Plain at the time of the 1955 survey.
