1971 Map of Old Baldy

About this map

Old Baldy rises above the rolling high plains of eastern Colorado in this 1971 study by the Department of the Interior. The landscape is characterized by its sparse settlement and the vital importance of groundwater, evidenced by several scattered wells and windmills throughout the quadrangle. Aside from the namesake summit, the terrain includes localized landmarks like Brophy and various structures marked Wm. This survey, produced from photogrammetric methods based on 1970 aerial photography, illustrates a moment in time when the remote corners of Yuma County remained largely dedicated to open range and isolated ranching operations. The detailed contour intervals reveal the subtle variations in elevation across this part of the Western Great Plains.
