2023 Map of High Rock

About this map

The San Francisco Mountains and Little Frisco Mountains dominate this high-desert landscape along the boundary of Millard Co and Beaver Co. This survey documents a critical basin-and-range corridor defined by seasonal water sources and steep topographic transitions. Remote landmarks like High Rock Pass and James Spring speak to the area's history of prospecting and ranching, where reliable water was the primary driver of human activity. The map traces the natural drainage patterns of Sawmill Canyon and Morehouse Canyon, offering a detailed view of the terrain before it gives way to the Beaver Lake Mountains in the southeast. This modern update by the U.S. Geological Survey preserves the nomenclature of early western exploration, including uniquely named features like Three Kilns Spring and Brownfield Canyon.
