1951 Map of Tatman Mountain

About this map

Tatman Mountain dominates this portion of the Bighorn Basin during the early 1950s, serving as a prominent topographic landmark at the boundary of Park and Big Horn counties. The survey, completed as part of the Missouri River Basin development program, details a network of drainage features such as Roach Gulch, Fenton Draw, and Blackburn Gulch that carve through the high-elevation landscape. The terrain is defined by steep ridges and significant survey points like Vabm 6295 Fenton, providing a clear picture of the land before modern energy development or intensive water management altered the natural drainage patterns. To the south, Sheets Mountain rises near Fenton Pass, illustrating the difficult passage through these uplands in an era when unimproved dirt roads and trails were the primary means of navigating the area.
