PLAYA LADOSA. Playa Ladosa, the name meaning "Beach of the Goose," is the broad estuary of the Aransas River and Chiltipin Creek in Aransas County, where the combined streams flow into Copano Bay (at 28°04' N, 97°14' W). Normally little water flows, and the Playa Ladosa is a broad flat lying between higher lands. It was part of the Callo del Aranzazu of the Spaniards. Its banks, small islands, and adjacent lands are dotted with former Indian camp sites. The surrounding flat, marshy terrain is surfaced by sand and dark clays that support mesquite and grasses.
