1967 Map of La Valley

About this map

La Valley sits along the northern edge of this high-elevation landscape, where the Sangre De Cristo Grant dominates the central and southern terrain. This 1967 field-checked survey reveals a complex drainage network vital to the region's historical geography, including Vallejos Creek and San Francisco Creek flowing from the eastern slopes. A Jeep Trail provides the primary access route through the rugged interior, winding between the headwaters of Torcido Creek and Jaroso Creek. The map documents a specific moment in Costilla County history, showing the traditional land divisions and the hydrological importance of watercourses like Rito Agua Azul and Alamosito Creek as they descend toward the San Luis Valley. This topography emphasizes the transition from the valley floor to the higher mountain watersheds of West Fork Costilla Creek and Willow Creek.
