1951 Map of Split Rock NW

About this map

Green Mountain and the Owl Hills dominate the southern portion of this mid-century survey, where the high desert terrain of Fremont County meets the foothills of the Granite Mountains. The landscape is defined by the drainage systems of Cottonwood Creek and its various forks, which flow northward toward the Sweetwater R valley. This area represents a classic Wyoming rangeland environment, where the scarcity of water is managed through features like the McIntosh Beaton Ditch. Remote windmills dot the plains, supporting livestock operations in a region where Splitrock serves as a primary topographic landmark. The map documents the early alignment of U.S. Route 287 as it traverses the northern plains, providing a vital transportation link through the high country before the modern interstate era.
