2011 Map of Whirlwind Valley SW

About this map

Swasey Mountain looms over this arid portion of Millard County, defining the western edge of a landscape shaped by intermittent water sources and high-desert infrastructure. The map documents a network of essential water points for ranching and wildlife, including Antelope Spring Reservoir, Soap Hollow Reservoir, and the seasonally variable Rain Lakes. These features are connected by established backcountry routes such as Death Canyon Rd and the historic alignment of Old 6 and 50, which transect the valley floor. The convergence of Tin Well Wash and Tin Well in the southeast corner further illustrates the importance of mapping every available water source in this desert terrain. The presence of Coyote Knolls and the drainage of Soap Hollow reveal a topography of subtle elevation changes that directed the placement of the area's few, isolated roads.
