1951 Map of Soap Holes

About this map

The Green Mountains dominate this high-desert region of central Wyoming, rising sharply toward the southern edge of the sheet near Crooks Mountain. This 1951 field check reveals a landscape primarily used for cattle ranching and early petroleum exploration, characterized by seasonal drainage patterns and high-altitude alkali flats known as the Soap Holes. Traces of the region's ranching heritage appear in the margin, while the map's interior highlights the rugged hydrology of Ice Slough and the winding course of Happy Springs Creek. A solitary Oil Well and the geodetic marker at VABM Green 7750 indicate the intersection of industrial survey work and the vast, open range. The drainage of Haypress Creek further defines the eastern terrain, showing how water sources dictated the movement and settlement patterns across this portion of Fremont County.
