Grass Creek Basin defines the central character of this high-elevation landscape in Hot Springs County, where the terrain is carved by a network of ephemeral watercourses. This 2017 survey shows a complex topography of uplifted landforms, most notably Blue Ridge, Ilo Ridge, and the eponymous Red Ridge. These ridges overlook deeply incised drainages like Sand Draw and Spring Gulch, reflecting a geological history defined by erosion and mineral extraction potential as suggested by Coalmine Draw.
