Extending some 244 km from the Rio Bravo (Rio Grande) on the north to the mouth of the Rio Soto la Marina (at La Pesca) on the south, Padre Island, Mexico is comprised locally of several barrier-beach segments separating the Laguna Madre de Tamaulipas from the Gulf of Mexico R. R. Lankford has characterized the Laguna Madre, located on the northeastern coast of Mexico, as a 'Gilbert-de Beaumont Barrier Lagoon', protected from the Gulf by current- and wave-generated sand barriers dating from within the last 5,000 years of relatively modern sea level. This presentation documents recent field observations and presents an updated geomorphologic classification of the Padre Island, Mexico, barrier-beach system.
