About this map

Ranchero Oil Field and the neighboring North Shears Oil Field dominate the high plains of Washington County in this mid-1970s landscape. The terrain is defined by a series of north-south running draws and intermittent watercourses, including the winding beds of Camp Creek, Surveyor Creek, and Brunker Creek. This era of the region is characterized by intensive energy extraction, with numerous sites such as Oil Well 2 and a Gravel Pit scattered across the township grid.

Faint red dashed lines indicating property fence lines provide a rare level of detail for local-history researchers tracing land use and grazing patterns. The map shows the transition of the high prairie from open range to a highly organized industrial and agricultural landscape, where petroleum infrastructure like the Belle Oil Field coexists with the natural drainage patterns of the Colorado plains.
