Dickie Ranch and Rhodes Ranch anchor this landscape in Hot Springs County, where the high plains are defined by an intricate network of seasonal drainages and cattle camps. The geography here is dominated by the namesake Twentyone Cr, along with its east and west forks, which join as they flow toward the southeastern corner of the quadrangle. The map reveals the ranching infrastructure of the early 21st century, showing how modern corridors like Grass Creek Rd and Cottonwood Creek Rd follow the natural topography established by the many creek beds. Notable landmarks such as Putney Flat and the remote Rankin Cow Camp illustrate the sparse but deliberate human imprint on the land. Water sources like Pershal Spring remain vital in this arid environment, while dramatic terrain features like Egbert Draw and Dugout Draw carve through the basin.
