The Luis Maria Baca No 4 Grant Boundary dominates this high-altitude landscape where the San Luis Valley meets the eastern foothills. This mid-1960s survey illustrates a region defined by complex hydrology and shifting sands, notably within the Great Sand Dunes National Monument. The reliance on artesian water is evident through numerous named water sources like Antelope Springs and the Sand Camp Flowing Well. A network of Jeep Trails provides the primary means of navigation across the Sand Dunes, connecting remote water points and monitoring stations across the Saguache and Alamosa county line. Drainages such as Sand Creek, Big Spring Creek, and Pole Creek trace the edge of the dunes, marking the unique intersection of desert-like formations and mountain runoff.
