About this map

The Nimmo Ranch and surrounding family-held properties define this high plains landscape in Laramie County during the early 1960s. The region is characterized by an extensive network of irrigation infrastructure, where Horse Creek Ditch No 1, Adamson Ditch No 1, and Cattle Ditch No 4 divert water from the meandering Horse Creek to support local ranching operations.

Topographically, the area is marked by deep drainage features like Paulson Draw, Kelley Draw, and Nimmo Draw, which channel seasonal runoff toward Bear Creek and Little Bear Creek. This period of the cattle economy is preserved here through the documentation of established homesteads, including Moyer Ranch, Horner Ranch, and Whitaker Ranch. The map also captures the industrial footprint of the era, noting a regional Pipeline and several Gravel Pits that served the development of this rural Wyoming territory.
