2021 Map of Tatman Mountain

About this map

Tatman Mtn and Sheets Mtn dominate this high-desert landscape in the Bighorn Basin, where complex erosion patterns have carved a network of deep drainages. The area is defined by sharp elevation changes, particularly around Fenton Pass and the steep descent into Fenton Draw. This 2021 survey illustrates the remote character of the boundary between Park and Big Horn counties, showing a land primarily utilized for its topographic relief rather than dense settlement. Water, though scarce, is traced through ephemeral systems like Willow Cr and the deep cuts of Roach Gulch and Blackburn Gulch. The absence of developed towns emphasizes the area's role as a rugged corridor within the larger Wyoming range-land system, marked only by the essential survey lines of the Public Land Survey System.
