About this map

The Rio Grande serves as the international boundary on this survey, separating the United States and Mexico. The landscape is dominated by a complex network of agricultural irrigation and drainage systems, including the Hansen Lateral, Island Drain, and the Fabens Waste Channel. These man-made water features cut across San Elizario Island and lead toward the Guadalupe Bridge, which provides a vital transit point over the river.

Transportation throughout this borderland follows the contours of the valley, with named routes like Island-Tornillo Rd and Wingo Reserve Rd connecting isolated farms and the Tornillo Spur. Residential patterns are evident along the northern edge near Alameda Ave, where several street names like Grace St and Cypress St indicate small pockets of development adjacent to the extensive canal systems that define the region's geography.
