1963 Map of Flagstone Mountain

About this map

Conchas Ranch sits as a primary point of human settlement within this 1963 landscape of high mesas and deep canyons in San Miguel County. The topography is defined by the massive Mesa de Yegua and Mesa Montosa, which rise above the winding path of the Conchas River. The map reveals a land utilized for ranching and water management, evidenced by the presence of a lone Cem and Harris Tank. This area, surveyed just before the mid-1960s, shows a network of light-duty and unimproved dirt roads that follow the natural contours of Harris Canyon and Conchas Canyon, connecting the high plateaus to the drainage basins below. The namesake Flagstone Mountain serves as a central landmark, illustrating the transition between the flat-topped mesas and the erosional features of Cañada Tulosa and Salitre Creek.
