2020 Map of Red Knolls

About this map

Red Knolls and the surrounding high desert of Millard County are defined by a complex network of ephemeral drainage and remote water management. In this arid basin, land use is centered on a series of catchments including Swasey Reservoir Number 4, Highway Reservoir, and Soap Wash Reservoir, which support livestock or local transit across the scrubland. The terrain is marked by significant topographical features such as Whirlwind Valley and the prominent Long Ridge to the south. Transport through this isolated landscape follows the historical corridor of Old 6 & 50, while secondary routes like Death Canyon Rd provide access to the deep washes and hollows. This 2020 survey illustrates how modern mapping continues to track the vital water resources and rugged physical geography of the Great Basin.
