About this map

Laguna Atascosa National Wildlife Refuge dominates the western coastline of the Laguna Madre in this mid-century coastal study. The map documents a landscape defined by shallow hypersaline waters and complex estuarine features, including the Arroyo Colorado Cutoff and the winding Resaca de los Cuates. The central bay is populated by a chain of namesake landforms, including Primero Island, Medio Island, and Ultimo Island, alongside the larger Horse Island and Caballo Island.
