About this map

Olga and the surrounding high desert of Cochise County are defined by a sparse network of ranching and transportation infrastructure. The Southern Pacific railroad corridor serves as the primary east-west artery, running parallel to a major Pipeline and service roads. This industrial spine cuts through an arid landscape where water management is critical, as evidenced by the presence of the Olga Detention Dam, West Well Detention Dam, and several designated wells like New Well and West Well.

Scattered ranching operations such as Triangle Ranch and Garrett Ranch are the primary markers of settlement, alongside the ephemeral course of the San Simon River. Notable localized industrial features include the Yellow Hammer Mill and several Borrow Pits near the rail line, while a Landing Strip and a Radio Facility indicate the area's role as a remote crossroads for transit and communication in the mid-1970s.
