About this map

The Nueces River winds through the southwestern corner of this La Salle County landscape, where the confluence with Las Raices Creek marks a distinct break in the brush country. The eponymous Charco Marrano Creek carves a path from the north, its drainage system defining much of the central terrain. While primarily rural and focused on ranching at the Black Ranch, the land shows significant industrial development following the discovery of petroleum and natural gas.

Energy infrastructure is a dominant theme of the 1970s, with a dense network of Gas Wells, scattered Oil Well sites, and an extensive Pipeline cutting across the survey area. These features, along with numerous exploratory Drill Hole locations, provide a look at the mid-century energy boom that transformed this part of South Texas from traditional cattle ranching into a vital resource extraction zone.
