Agricultural development and early irrigation systems define this 1929 survey of the Rio Grande Valley. The town of Santa Rosa serves as a primary hub at the intersection of the Southern Pacific RR and the St Louis Brownsville and Mexico RR, illustrating the critical role of rail transport in the regional economy. The landscape is marked by a transition from large, established cattle estates like Santa Rita Ranch and El Grullo Ranch to a grid of irrigation canals and roads that supported the area's emerging citrus and vegetable industries.
