Beaver River and Lefthead River define the interior drainage of this wild section of the Alaska Peninsula. The landscape transitions from the broad Buck Valley in the north to the sharp rise of Hoodoo Mtn in the southwest corner. This 2020 survey reveals an environment shaped by water and elevation, where the expansive Sapsuk Lake sits at the base of steep topographic contours. The mapping of township and range lines, including t52s r76w and t51s r75w, provides a structural framework for this remote terrain. For researchers and geologists, the map captures the untouched hydrological patterns of the Aleutians East Borough, showing how these river systems navigate the deep valleys and mountain foothills.
