The town of San Luis stands as a central hub on this high-altitude landscape, where the ancient and essential practice of irrigation is clearly documented. The map reveals an intricate network of waterways supporting the valley, including the historic San Luis Peoples Ditch and the Cerro Ditch Number 2. These systems draw from Culebra Creek and Rito Seco to sustain a string of small settlements. Traveling south along the base of the prominent San Pedro Mesa, the landscape transitions through the communities of San Pedro, San Pablo, and Chama. For those researching family roots in Costilla County, the presence of the San Pedro Cemetery and residential grids like those on Casa Verde Real and Alfonso St offer precise geographic points of interest. The area’s modern utility is also represented by the San Luis Airport and the expansive Salazar Reservoir, reflecting a balance of historical agriculture and regional infrastructure.
