1956 Map of Charley River D-1

USGS Topo · Published 1974

About this map

Charley River meanders across the lower portion of this 1956 terrain study, tracing a path through the wilderness just west of the United States Canada border. This region, captured via photogrammetric methods from 1955 aerial photography, is defined by its complex drainage systems and unique permafrost formations. The presence of Pingos highlights the specific Arctic geomorphology of the area, offering a rare look at these earth-covered ice mounds as they were documented in the mid-1950s. Tributaries such as Bull Creek, Midnight Creek, and Surveyor Creek feed into the larger river system, illustrating the watershed of the eastern interior before modern environmental changes. The map provides a critical record of the Alaska Yukon boundary, where surveying control was established by the International Boundary Commission and the U.S. Geological Survey.
