1952 Map of Cottonwood Pass

About this map

Lysite Mountain and the southern reaches of the Bighorn Mountains define this high-altitude landscape along the triple-point boundary of Hot Springs, Fremont, and Natrona counties. Mapped as part of a Missouri River Basin development program, the area is characterized by a network of seasonal water sources and early livestock operations. Genealogy researchers can find several designated family sites, including the active Nichols Ranch and Britain Ranch, alongside several locations already noted as deserted by the early 1950s.
