1986 Map of Jacks Knob

About this map

Jacks Knob serves as a central landmark for this arid high-desert landscape situated along the border of Emery Co and Wayne Co. The terrain is defined by dramatic geological formations, most notably the towering Red Reef in the north and Sweetwater Reef to the southwest, which create distinct natural barriers across the quadrangle. Water sources are scarce and localized, represented by specialized features like Moonshine Well and the remote Twin Springs near the entrance to Middle Canyon. This 1980s field revision records the distribution of vital water points, including Dugout Spring and Upper Dugout Spring, which historically supported cattle ranching and seasonal movement through the region's expansive washes. The map captures a moment when traditional land use patterns remained evident through these named springs and the network of primitive routes connecting them.
