North Knoll Spring serves as a vital water source in this arid corner of Millard County, situated near the intersection of several township boundaries including t18s r18w and t18s r17w. The landscape is defined by elevated terrain features like Plympton Ridge and Rattlesnake Bench, which overlook the seasonal drainage of Browns Wash. Transportation through this remote high-desert environment relies on a network of unpaved routes, most notably Foot Ranch Rd and Browns Wash Rd, which provide access to the area's grazing lands and the drainage of Red Gulch. The map illustrates the sparse infrastructure and essential water points required for ranching operations in the eastern Great Basin during the early 21st century.
