About this map

The drainage patterns of Irion County are the defining characteristic of this terrain, where Big Hollow Draw and Seep Draw cut through the West Texas plateau. The landscape is a network of intermittent watercourses including Rock Pen Draw and the headwaters of Lopez Cr, illustrating the hydrological challenges of this semi-arid region. Unlike more densely populated Texas quadrangles, this area is defined by its rural connectivity and vast ranchlands.

Transportation is limited to a sparse grid of maintained roads, primarily Fm 2469 and localized paths like Andy Suggs Rd and Shay Rd. These routes provide essential access to the interior rangelands, which are further dissected by a series of county roads such as Co Rd 412 and Co RD 410. This modern topographic study reveals the enduring character of the Edwards Plateau, where the few named features often relate to family ranching history or natural draws.
