1972 Map of Whirlwind Valley SW

About this map

Swasey Mountain dominates the northwestern portion of this 1972 survey, its steep contours rising sharply above the desert floor of Whirlwind Valley. The landscape reveals a critical reliance on seasonal water management in this arid stretch of Millard County, marked by features such as Antelope Spring Reservoir and the distant Soap Hollow Reservoir. The topography transitions from high peaks into the alluvial fans of the Coyote Knolls, where the terrain flattens toward intermittent water sources. Evidence of livestock or travel infrastructure appears in the lower elevations through the presence of Tin Well and Rain Lakes. While the area lacks permanent settlements, the placement of the Gravel Pit and scattered wells suggests a landscape utilized for its raw materials and grazing potential during the early 1970s.
