About this map

Laguna Atascosa defines the western edge of this coastal reach, where the South Texas brush meets the marshy transitions of the Lower Rio Grande Valley. The landscape is a network of peninsulas and small islands, including Rincon de Guajardo and El Realito Peninsula, separated by the shallow waters of El Realito Bay. The mapping of Buena Vista Blvd and the Rancho Buena Vista Airport indicates the modern infrastructure supporting the area's light settlement at Rincon Buena Vista.

Navigational arteries like the Intracoastal Waterway and the Arroyo Colorado Cutoff demonstrate the importance of marine traffic through the Laguna Madre. The eastern portion of the sheet is dominated by the expansive sands of Padre Island, while inland, a series of specialized trails such as the Bobcat Trl and Upper Cayo Loop Trl provide access across the protected wetlands and up toward Red Head Bluff.
