 Soon afterward, Cabeza de Vaca and his crew were shipwrecked on the island (or nearby) in November 1528, calling it ""Isla de Malhado"" ("Isle of Doom"), and from there began his famous trek to Mexico.Various Spanish explorers charting the region referred to the island as "Isla Blanca" ("White Island") and later "Isla de Aranjuez" ("Aranjuez Island").In 1685 French explorer La Salle named the island "San Louis" ("Saint Louis") and the name became fixed for some time.
