The Luis Maria Baca Grant No 4 meets the shifting landscape of the Great Sand Dunes National Park in this 2001 revision of the Saguache and Alamosa county borderlands. The map documents the transition of these dunes into a national park and preserve, capturing a region defined by high-altitude drainages like Medano Creek and Cold Creek. Small historical settlements like Liberty and Duncan sit at the base of the Sangre De Cristo Mountains, while the rugged interior is marked by a solitary Grave and mining efforts like Prospect X. The intricate topography reveals the complex hydrology of the San Luis Valley, where water from Pole Creek and Cleveland Creek disappears into the massive sand deposits. This survey serves as a vital record of the wilderness and forest boundaries before the 21st-century management changes were fully implemented.
