2019 Map of McGrath A-2 SW

About this map

The Alaska Range dominates the high-altitude terrain of this interior landscape, where steep contour lines and glacial drainages define the wilderness boundary between the Yukon-Koyukuk Census Area and the Bethel Census Area. This specific quadrangle captures a remote section of the Kuskokwim drainage basin, centered on the winding path of the Windy Fork Middle Fork Kuskokwim River as it cuts through the southwestern reaches of the range. The mapping reveals a complex network of high ridges and narrow valleys, illustrating the extreme topography that has historically dictated travel and access in this part of the Alaskan bush. Without roads or permanent settlements, the map documents the natural hydrology and land divisions that govern this unpopulated expanse, providing a precise topographic record of the area as it existed in 2019.
