Red Knolls rises as a prominent landmark above the surrounding desert terrain of Whirlwind Valley in this Millard County landscape. The area is defined by a complex network of dry watercourses, including Tin Well Wash, Soap Wash, and Swasey Wash, which signal the movement of seasonal water across the arid basin. Human presence is marked by infrastructure adapted to this environment, such as Swasey Reservoir Number 4 and the Highway Reservoir. These water management features, along with Soap Wash Reservoir and Swasey Wash Reservoir, indicate the importance of livestock and resource management in this part of Utah. The western edge of the valley is constrained by the elevation of Long Ridge, while navigation through the terrain relies on primitive routes like Death Canyon Rd and the historical corridor of Old 6 & 50.
