2011 Map of Whirlwind Valley NW

About this map

Whirlwind Valley and the surrounding high desert of Millard County are defined by a network of drainage channels and remote water catchments. The landscape is dominated by the broad Swasey Bottom and the rugged slopes of Swasey Mountain, with drainage features such as Swasey Wash cutting through the arid terrain. Human activity in this remote region is marked by livestock water infrastructure, specifically Swasey Reservoir Number 2 and Swasey Reservoir Number 3. These features reflect the long-standing importance of water management in the Great Basin. The prominence of Black Point provides a clear geographical marker in this expansive territory, while the map's network of local roads and 4WD tracks indicates the primary routes used by ranchers and land managers navigating the valley floor and foothills in the early 21st century.
