2016 Map of Survey Pass A-1 SW

About this map

Alatna River meanders extensively through this portion of the Yukon-Koyukuk region, creating a complex network of oxbows and riparian wetlands. The landscape is defined by the sharp contrast between the wide, low-lying river valley and the rising elevations of the Helpmejack Hills to the southwest. This 2016 survey illustrates the fluid nature of Arctic waterways, where the river's course shifts over time, leaving behind numerous sloughs and side channels. Tributaries like Lake Cr feed into the primary basin, carving through the surrounding terrain. This map serves as a modern record of a remote wilderness area, highlighting the intricate hydrology and topography of the Brooks Range foothills where the land remains largely untouched by permanent human infrastructure or road networks.
