About this map

Twentymile Waterhole sits at the heart of this landscape in Schleicher County, a vital point for water management in an area defined by its drainage systems. The terrain is marked by significant geographic depressions and valleys, including Live Oak Hollow and Lake Hollow in the north and the broader North Valley further south. These features are primarily drained by the N Valley Prong, which snakes through the central portion of the quadrangle. The sparse road network, consisting of routes like Co Rd 220 and Co Rd 224, reflects the rural and ranching-oriented character of the Edwards Plateau. The spatial arrangement of named waterholes and hollows provides clear evidence of how natural topography dictates land use and accessibility in this part of West Texas.
