2010 Map of Sarnosa Hill

About this map

Lundell Oil Field and several neighboring petroleum operations define the industrial character of this Duval County landscape, where the energy economy is deeply integrated into large ranching tracts. The map illustrates a complex network of access roads and infrastructure supporting both oil extraction and cattle ranching, most notably at the Duval Ranch. Water management is critical in this brush country environment, as evidenced by the Duval County Ranch Colmena Tank Dam and Colmena Tank, which capture drainage from Colmena Creek. Topographically, the area is punctuated by modest elevations like Sarnosa Hill and Cedro Hill, providing landmarks across the varied terrain. The presence of the Duval County Ranch Company Airport further highlights the scale of these private holdings during the early 21st century.
