About this map

The North Fork Kuskokwim River meanders through the heart of this interior Alaskan wilderness, defining a landscape dominated by complex fluvial patterns and alluvial floodplains. To the east, the topography rises sharply into the East Fork Hills, where the contour lines tighten to reveal the transition from riparian lowlands to upland terrain. Tributaries such as Wolverine Cr and Lake Cr feed into the primary river system, illustrating the drainage network of the Yukon-Koyukuk region. This 2019 survey, produced by the U.S. Geological Survey, provides a detailed record of watercourse placement and elevation changes in a remote section of the Unorganized Borough, where the natural hydrology remains the primary structural element of the territory.
