2019 Map of McGrath A-1 NW

USGS Topo · Published 2019

About this map

The South Fork Kuskokwim River defines the central corridor of this Alaskan wilderness, winding through a high-elevation landscape where the Yukon-Koyukuk and Bethel Census Area boundaries meet. The terrain is marked by significant vertical relief, rising from the braided river valley to prominent heights such as Knox Peak. Steep geographical features like Graptolite Canyon and Barren Rid indicate a landscape shaped by significant erosion and geological force, while several smaller drainages including Wolverine Cr and Brush Cr feed into the primary river system. This survey illustrates the intricate tributary network of the Kuskokwim watershed in a region characterized by its lack of road infrastructure, where the primary movement and geography follow natural watercourses and mountain ridgelines.
