2010 Map of La Union

About this map

The fertile Mesilla Valley defines the character of this landscape at the edge of New Mexico and Texas, where a complex network of irrigation and drainage systems supports the agricultural land around La Union. The intricate placement of water features like La Union West Lateral, La Union East Lateral, and West Drain illustrates the sophisticated water management required in this arid river valley. These channels, along with others like Talbot Lateral and Deck Lateral, divide the land into a geometric grid of fields and farm roads. Toward the south, the terrain transitions as it approaches the Santa Teresa Airport, while the western portion of the map is dominated by the long, straight reaches of County Rd A089 and Santa Teresa International Blvd, connecting the valley to the higher desert plateaus beyond.
