1951 Map of Split Rock NW

About this map

The Sweetwater River flows through the northern reaches of this Wyoming landscape, framed by the distinctive geological formations of Sweetwater Rocks. Surveyed for the development of the Missouri River Basin, the map illustrates an arid high-desert terrain where water management is critical for ranching, evidenced by the presence of Beaton Ditch and numerous isolated Windmills. To the south, the topography rises sharply into the Green Mountains and Owl Hills, cut by the rugged Rocky Canyon. A complex network of drainage is visible where Cottonwood Creek splits into its West Fork, Middle Fork, and East Fork. The survey also marks the high point at VABM Splitrock 6612, providing a detailed view of the Fremont County wilderness during the mid-century era of western water resource planning.
