1965 Map of Blanca SE
USGS Topo · Published 1968About this map
The San Luis Hills and the Sangre De Cristo range converge in this mid-1960s study of Costilla County terrain. This landscape is defined by its arid hydrology and complex elevation, marked by the western flow of Trinchera Creek and the man-made irrigation of the Trinchera Canal in the northeast. The presence of a Substa and multiple Well points indicates the managed development of the San Luis Valley during this era, where water infrastructure was essential for the surrounding land.
