1957 Map of Twin Buttes

About this map

The Middle Concho River valley south of San Angelo is defined here by its mid-century transformation into a major water management hub. This 1957 survey, updated with late-1970s revisions, illustrates the expansive Twin Buttes Reservoir and its relationship to the older Lake Nasworthy downstream. The landscape is a mix of industrial resource extraction and spiritual landmarks, featuring the Pulliam Oil Field and scattered Gravel Pits alongside the Chapel-on-the-Hill. The Atchison Topeka and Santa Fe railroad cuts a straight diagonal across the southwestern terrain, bypassing the distinctive natural rises of the Twin Buttes. Further north, the shoreline of O C Fisher Lake meets the jagged topography near Pulliam Pt, while a network of service infrastructure like Arden Road and various pipelines connect the oil-producing uplands to the river basin.
