About this map

The Emigrant Trail (Sublette Cutoff) traverses the southern reaches of this Lincoln County landscape, marking a historical corridor of westward expansion across the high Wyoming terrain. The topography is dominated by north-south trending formations, including the prominent South Fork Mountain and the parallel crests of Commissary Ridge and Oyster Ridge. Between these heights lies Mammoth Hollow, a significant drainage area where the Coal Branch and Everly Creek gather.

A network of seasonal watercourses and ridges defines the area, with Granny Peak serving as a high point overlooking Lake Creek and Boney Canyon. In the southeast, Pomeroy Basin and the Mud Lakes suggest a lower, more varied relief near Wright Divide. The survey details the remote cattle and sheep country of the mid-1960s, evidenced by features such as Corral Creek and Sheep Dip Creek, reflecting the region's long-standing reliance on pastoral land use.
