1955 Map of De Long Mountains A-1

About this map

The Kelly River and Avan River systems converge in this remote Arctic wilderness, illustrating the braided drainage patterns characteristic of the Brooks Range foothills. Based on aerial photography and field annotations from the mid-1950s, the map reveals a landscape defined by seasonal water flow and high-latitude topography. To the southeast, Lake Tagagkvik sits as a prominent landmark in an area largely devoid of permanent human infrastructure. The presence of Wrench Creek cutting through the western mountains highlights the topographic complexity of the terrain. Prepared by the Army Map Service and the Geological Survey, this sheet serves as a primary record of the region before modern development, noting land lines that were predetermined by the Bureau of Land Management but remained unsurveyed on the ground at the time of publication.
