About this map

S Fork Powder River and its various tributaries, including Cloud Cr and Lone Tree Cr, define the drainage patterns of this high-plains landscape in Natrona County. Ranching infrastructure and remote camps are central to the human footprint here, as evidenced by Powder River Corral and the Jack Ellis Camp. A network of unpaved corridors like Harlan Ranch Rd and Lone Bear Rd provide the primary access to cattle operations and water management sites such as Blue Hill Reservoir.

The terrain is marked by distinctive geological features and draws, from the prominent Fiftymile Flat to the narrow passage of The Gap. Small-scale reservoirs like Three T Reservoir and named drainage basins including Stone and Timber Draw and Big Sulfur Draw highlight the critical importance of water rights and land management in this arid Wyoming region. Historical movement through the area is suggested by the Wild Horse Trl, which cuts across the central part of the quadrangle.
