1964 Map of Eldorado NE

About this map

The South Concho River carves a central path through this section of Schleicher County, shaping a landscape defined by significant energy production and transport history. The Hulldale Oil Field and Eldorado Gas Field dominate the northern and southwestern portions of the quadrangle, where numerous wells and pipelines illustrate the intensity of mid-century petroleum extraction. An Old Railroad Grade runs parallel to the river and Highway 277, tracing a defunct transportation corridor through the scrub and limestone hills. Genealogical markers appear at a small Cem near the riverbanks, while the rugged geography is named at Eldorado Canyon and various drainages like Whitten Draw and Milligan Draw. This 1964 survey, updated with 1979 aerial data, captures the intersection of the region's natural drainage patterns with its deep-seated industrial infrastructure.
