The San Juan River snakes through the high desert landscape of the Four Corners region, where the borders of Utah and Colorado meet. This map illustrates a transition point in the river's path as it flows west, flanked by the dramatic elevation of Yellow Rock Point. The landscape is defined by intermittent drainages such as Cowboy Wash and Toh Dahstini Wash, which reveal the erosive forces shaping the Shiprock Agency lands. Unlike more developed regions, this area is marked by a sparse network of local routes including C R 412 and C R 414, which follow the natural contours of the river valley. The proximity to the Four Corners monument makes this a significant study of the interstate boundary before the river continues its descent toward the Colorado River system.
