2010 Map of Three Islands

About this map

Laguna Madre dominates this coastal landscape, where a chain of islets and points defines the interface between the mainland and the bay. The map illustrates the complex hydrography of the region, including the Arroyo Colorado Cutoff and the Intracoastal Waterway channel that cuts through the shallow waters. Notable terrain features like Horse Island, Rattlesnake Island, and the group known as Three Islands—comprising Medio Island, Primero Island, and Ultimo Island—serve as key landmarks for maritime navigation and local history. To the south, the El Realito Peninsula and Rincon de Guajardo frame El Realito Bay, while the Rancho Buena Vista Airport and Buena Vista Blvd indicate the modern infrastructure serving this stretch of the Texas Gulf Coast.
