Stepladder Mountains dominate the eastern reaches of this 1985 survey, providing a sharp topographic contrast to the broad expanse of Ward Valley to the west. This arid landscape in San Bernardino County is defined by its drainage patterns, most notably the braided course of Homer Wash as it travels southward through the valley floor. The map records a sparsely developed desert environment where land management is delineated by the grid of Townships 5 and 6 North and Ranges 19 and 20 East. Apart from the natural terrain, the most distinct human or survey marker is the point labeled Avis in the southwestern quadrant, situated near the valley bottom. The lack of major infrastructure or settlements during this mid-1980s period highlights the preserve of wilderness and open range typical of the Mojave desert region.
