2015 Map of Ophir B-4 SW

About this map

Grouch Cr winds through the interior landscape of the Yukon-Koyukuk region, defining the drainage patterns of this Alaskan territory. The terrain is marked by the shifting course of this primary watercourse as it meanders between subtle elevations, a characteristic feature of the state's vast river systems. Surveyed for the U.S. Geological Survey, this 2015 study documents the Public Land Survey System grid across multiple townships, including t24s r5e and t25s r6e. The map provides a precise look at the hydrography and contour elevations of this specific quadrant before more recent environmental changes, offering a primary source for researchers studying the geography of the Alaska interior.
