About this map

Emigrant Gap Ridge dominates the southern portion of this landscape, serving as a prominent topographic divide in this part of Natrona County. Below the ridge, the land is defined by a complex network of water management, featuring the Casper Canal, Bishop Lateral, and Johnson Canal. These features indicate the critical role of irrigation in sustaining the livestock and ranching operations of the era, such as the Thirtythree Mile Ranch located near the intersection of Thirtythree Mile Road and Telephone Road.

Drainage patterns are clearly marked by several named ephemeral watercourses, including Twelvemile Draw, Sixmile Draw, and South Fork Casper Creek. The presence of numerous pipelines and a Radio Tower suggest the infrastructure of the mid-twentieth century energy and communication sectors. This survey, updated in 1960, provides a clear view of the high plains ranching economy before modern expansion.
