2017 Map of Ophir D-3 SE

About this map

Wapoo Hills dominate the southern half of this landscape in the Yukon-Koyukuk Census Area, rising as a prominent upland within the interior of Alaska. This 2017 survey details the complex drainage patterns of the region, where Wapoo Cr winds through the central and southern valleys while Galatea Cr cuts across the northern portion of the quadrangle. The map is defined by its topographic detail, illustrating the rhythmic undulations of the hills and the winding courses of these two primary waterways. These features represent the characteristic interior Alaska terrain, where water systems and elevation changes dictate the natural movement across the land. The presence of these named geographic features provides a clear reference for the physical geography of this specific sector, situated within the Public Land Survey System grids of t19s r8e, t19s r9e, and t20s r8e.
