2016 Map of Blanca SE

About this map

San Luis Hills dominate the southern landscape of this Costilla County region, where the high desert terrain meets a highly structured grid of modern rural development. The area is defined by an extensive network of numbered roads, including 33rd St and Co Rd 10, which stretch across the plains in a precise geometric pattern that suggests late-twentieth-century land subdivision. To the north, water management is evident through the path of Trinchera Cr and the Trinchera Canal, vital lifelines for agriculture in this arid environment. The map details the transition from the distinct topographic relief of the hills to the flat, subdivided expanses that characterize much of the San Luis Valley's eastern edge near the Rio Grande county line.
