1972 Map of Mertzon SW

USGS Topo · Published 1988

About this map

The Middle Concho River traverses the northern edge of this Irion County landscape, where the terrain is defined by a series of significant drainage systems including Big Hollow Draw and Seep Draw. This 1972 survey, later updated with revisions in the mid-1980s, reveals a rural Texas environment transitioning between traditional ranching and mid-century industrial expansion. Evidence of resource extraction is prominent throughout the quadrangle, with numerous Gravel Pits and various Drill Hole locations marking the hillsides. The southern reaches are characterized by the winding path of Lopez Creek and the long expanse of Rock Pen Draw, while scattered infrastructure like a prominent Radio Tower and an Oil Well punctuate the open country, showing the technological footprint of the era on the Edwards Plateau.
