1969 Map of Boise City SE

About this map

The Oklahoma Texas state line serves as the southern anchor for this 1969 topographic survey, marking the jurisdictional divide between Cimarron Co, Oklahoma, and Dallam Co, Texas. The landscape is defined by the broad upland terrain of Cleveland, where the surveyor’s Base Line establishes the geometric order of the High Plains. Unlike the dense settlement patterns of more eastern regions, this corner of the Panhandle is characterized by its wide-open cattle and agricultural spaces. The map reveals the critical infrastructure of a semi-arid landscape, specifically the distribution of dozens of labeled Wells that sustained ranching operations across the section lines. These water sources, often located near lone structures or windmills, illustrate the essential reliance on groundwater in this high-altitude prairie region before modern irrigation reshaped the local economy.
