The Rio Grande Delta in the early 1960s serves as a busy corridor of international transit and coastal industry. This survey illustrates the intricate landscape of the Lower Rio Grande Valley, where the Rio Grande marks the border between Texas and Mexico. Near the coast, the Laguna Atascosa National Wildlife Refuge preserves the shoreline of Laguna Madre, while offshore, Padre Island and Boca Chica Island shield the mainland from the Gulf of Mexico.
