Boulder Cr meanders across this northern landscape, serving as the primary drainage through a vast expanse of unpopulated territory. This survey, compiled from data ranging from 2001 to 2018, documents a region defined by its physical geography rather than human infrastructure, with no roads, buildings, or named settlements present on the sheet. The terrain is organized by the Public Land Survey System, showing the intersections of t32n r20e, t32n r21e, t31n r20e, and t31n r21e. For those studying the Yukon-Koyukuk region, this map provides an essential baseline of the natural drainage patterns and topographical contours that dictate movement through this interior wilderness.
