2012 Map of Bob Thompson Peak

About this map

Bob Thompson Peak anchors this corner of the Arizona-Sonora borderlands, where the high desert terrain transitions into the riparian corridor of the San Pedro River. The landscape is defined by established cattle operations and rural homesteads, including Montezuma Ranch, Zalesk Ranch, and Brown Ranch. In the north, Montezuma Canyon cuts through the elevation, while the plains are marked by a grid of local ranch roads like S Kings Ranch Rd and S Samuel Rd. Human impact on the land is further evidenced by Evelyn Field Airport near the northeastern boundary. Along the southern edge, Border Rd and S Border Monument Rd trace the international boundary, highlighting the remote yet structured nature of this border region during the early 21st century. The map provides a clear look at how water, elevation, and property lines dictate the layout of this high-altitude environment.
