1951 Map of Allyns Bight

About this map

St Joseph Island dominates this coastal survey, appearing as a dynamic barrier landform shaped by shifting sands and the relentless energy of the Gulf of Mexico. Along the bay side, the topography is defined by intricate Sand and Mud Flats and narrow waterways, including Blind Pass and the secluded Allyn Lake. A small Landing Strip on the island provides a lone indicator of human infrastructure amidst the shifting sand dunes that reach heights of up to 25 feet. The boundary between the shallow waters of Aransas Bay and the deeper gulf is marked by the eponymous Allyns Bight, a pocket of water sheltered by the island’s inward curve. This 1951 field check captures the Texas coastline before modern development, documenting the natural state of Mud Island and the complex tidal margins of the Aransas County shore.
