2011 Map of Red Knolls

About this map

Whirlwind Valley and the distinctive Red Knolls terrain dominate this Millard County landscape, which is defined by its arid drainage systems and remote road network. The map reveals an intricate water management system essential for this dry region, featuring Swasey Reservoir Number 4, the Swasey Wash Reservoir, and the Soap Wash Reservoir. These catchments follow the natural seasonal flow of Swasey Wash and Soap Wash. Transportation through this territory is anchored by the historic alignment of Old 6 and 50, which skirts Soap Hollow as it traverses the desert floor. The inclusion of the Highway Reservoir near the roadway further emphasizes the critical importance of water resources for travelers and local use in this part of western Utah, while Long Ridge provides a prominent geological boundary in the southern portion of the quadrangle.
