The urban corridor of the Rio Grande Valley emerges in this mid-1960s study, anchored by McAllen, Pharr, and San Juan. The landscape reflects a transition from intensive agriculture to regional industrial and aviation hubs, centered on Miller International Airport and the surrounding network of irrigation and infrastructure. The map reveals the critical importance of water management in the region, dominated by the Main Floodway and the Hackney Lake Inlet, which bypasses the sprawling Pharr Gas Field and Hidalgo Gas Field.
