About this map

Grave Spring serves as a central landmark in this high-altitude section of the Bighorn Mountains, where the headwaters of several major creek systems begin their descent. The drainage patterns are well-defined by the Middle Fork Powder River in the northwest and a complex network of Buffalo Creek branches, including the N Fork Buffalo Cr, Middle Fork Buffalo Cr, and S Fork Buffalo Cr. These water sources were historically vital for livestock and early travel through this portion of Natrona County.

Transportation through this high country is dictated by the steep topography, centered on the Bighorn Mountain Rd and the Bighorn Trl. The map also identifies remote watering points such as First Water Draw and First Water Cr, which highlight the importance of localized hydrology in the arid Wyoming landscape. Boundaries for several townships, including t40n r86w, intersect here, marking out the vast grazing and resource lands typical of the region.
