1979 Map of Rush Valley

Evidence of the area's pioneer and mining history is preserved at the Camp Floyd State Historical Site near Fairfield, while smaller mining settlements like Ophir and Mercur sit in the mountain canyons. The Union Pacific Railroad cuts a north-south line through the center, connecting agricultural and ranching outposts such as St John, Clover, and Vernon. Local landmarks like Simpson Buttes and the Sinks highlight the complex drainage patterns of these arid basins.
