2017 Map of Beaver B-4 NW
USGS Topo · Published 2017About this map
Boundaries defined by the Public Land Survey System divide this northern landscape within the Yukon-Koyukuk region, specifically where T19n R6w meets T19n R7w. The terrain is characterized by a high concentration of wetlands and drainage patterns that weave through the northern interior of Alaska. This 2017 survey by the U.S. Geological Survey utilizes satellite imagery and elevation data to trace the subtle shifts in topography across the townships of T18n R6w and T18n R7w. The absence of roads or established settlements emphasizes the undisturbed nature of this wilderness, where the mapping focuses on the hydrography and wetland systems that dominate the local ecosystem.
