2010 Map of Blanca SE

About this map

Trinchera Creek winds through the northwestern corner of this high-altitude landscape, feeding into a grid-iron network of irrigation and infrastructure. The area is defined by its agricultural layout, where the Trinchera Canal and a dense system of county roads, such as County Rd-108 and Arapaho Ave, organize the terrain into a sprawling patchwork of potential farmland. To the south and east, the natural topography breaks the man-made grid as the San Luis Hills and the Basaltic Hills rise from the valley floor. This intersection of systematic land division and volcanic geology reflects the late 20th-century development of water rights and rural access in the San Luis Valley. The map captures the specialized road numbering system, including corridors like County Rd-100 and named thoroughfares like Navajo Ave, which facilitate movement between the hills and the cultivated basins.
