2012 Map of Fourmile Reservoir

About this map

Reno Hill Anticline dominates the central landscape of this 2012 Johnson County survey, a geological signature of the Powder River Basin. The area is defined by its drainage network, where N Fork Fourmile Cr and Fourmile Cr converge near the Four Mile Reservoir. This high-plains terrain is largely navigated via the Buffalo Sussex-Cutoff Rd, which passes by Reno Hill in the northeast. The map provides a detailed view of the regional hydrology and topography, capturing named ephemeral features like Voelkner Draw, Taylor Draw, and Truk Draw. These drainages, alongside N Prong Soldier Cr, illustrate the complex erosion patterns that characterize the ranching and energy-producing lands of north-central Wyoming.
