About this map

Big Hollow Draw and several other ephemeral drainages carve through this section of the Edwards Plateau in southwest Irion County. The landscape is defined by its complex topography, where deeply incised valleys like Rock Pen Draw and Seep Draw reveal a rugged ranching environment. Transportation in this arid region is sparse, consisting primarily of county roads and farm-to-market routes such as Fm 2469. These roads often follow the natural contours of the land or cut directly across the high divides between watercourses. In the eastern portion of the map, Lopez Cr provides a primary drainage point, while named ranch roads like Andy Suggs Rd and Shay Rd suggest the localized importance of specific landholdings and family-named access points in this rural West Texas expanse.
