About this map

The Bighorn Mountains dominate the northwestern horizon of this Central Wyoming survey, giving way to a high-desert landscape defined by complex water systems and energy production. The southern portion of the sheet highlights the transition from the Sand Hills into the ranching and railroad corridor served by the Burlington Northern line, connecting stops like Arminto and Petrie Siding.

Crucial for historical research, this edition records the location of the Teapot Dome Naval Petroleum Reserve No 3 and its proximity to iconic landmarks like Teapot Rock and Castle Rock. The map tracks the vital waterways of the South Fork Powder River and Salt Creek, revealing a landscape where remote outposts like Otter Creek Ranch and the Fort Reno (Historical marker) mark the enduring patterns of settlement and frontier defense in the high plains.
