1958 Map of Arminto

About this map

The Big Horn Mountains dominate the northwestern horizon of this central Wyoming landscape, transitioning into the expansive Sand Hills and Ralston Flats. Small settlements like Arminto, Waltman, and Hiland dot the high plains, many serving as critical stops along the Chicago Burlington and Quincy railroad line. The presence of the U S Naval Petroleum Reservoir and numerous oil wells near Midwest and Edgerton signals the region's mid-century energy production, particularly in the Salt Creek area.
