1971 Map of Rocky Knoll

About this map

The Old Channel Sevier River winds through the desert landscape of Millard County in the early 1970s, revealing a complex network of seasonal water management and natural hydrology. This arid terrain is defined by its depressions and Sand Dunes, where water sources like Rocky Knoll Spring and Soda Spring provided critical points of relief. The presence of numerous Borrow Pits and various reservoirs, including Tamarack Reservoir and Hardpan Reservoir, suggests the ongoing efforts to capture and redirect the scarce water of Soap Wash for regional needs. A lone Corral near the river channel and a scattered system of wells, such as the Soda Well, indicate the area's use for livestock and land management. The map documents the intricate balance between the desert's natural features and the infrastructure required to sustain activity in this part of the Great Basin.
