2022 Map of Blanca SE

About this map

The San Luis Hills dominate the southern landscape of this Costilla County area, revealing a complex topography of volcanic rises and high-desert basins. This 2022 survey illustrates a rigid grid of rural roads, such as Co Rd X and Co Rd 12, which partition the dry terrain into expansive sections typical of the San Luis Valley's land management history. In the northeastern corner, the Trinchera Canal cuts across the contours, marking a vital piece of water infrastructure in this arid region. The network of named avenues and streets, including Alyssium Ave and Jefferson Rd, indicates a planned rural development pattern where few traditional town centers exist, but the infrastructure for land access is clearly established.
