1990 Map of Register Cliff

About this map

The Oregon Trail passes through this section of Wyoming, marking a landscape defined by pioneer migration and early Western infrastructure. Register Cliff, a prominent landmark where emigrants carved their names into soft sandstone, is preserved alongside the Reg. Hist. Cliff Historical Monument and the site of a Pony Express Station. This area, near the Old Guernsey Ranch, shows the convergence of the North Platte River and the Laramie River, which support local agriculture via the Whalen Diversion Dam and various siphons and ditches. The terrain transitions from the open Bettelyoun Flats to the elevations of Mummy Mountain, while much of the northwest is occupied by the Camp Guernsey State Military Reservation. In the south, the expansive Grayrocks Reservoir dominates the drainage of the Laramie River, reflecting modern water management alongside nineteenth-century trail history.
