Padre Island National Seashore protects this section of the Texas coast, where the barrier island meets the open waters of the Gulf of Mexico. The geography is defined by a narrow strip of land on Padre Island that separates the surf from the mainland marshes further west. This survey illustrates the delicate nature of the coastline, showing the shifting sands and low elevation characteristic of the Kenedy County shore. The absence of roads or developed infrastructure emphasizes the preserved and natural state of this coastal environment, serving as a baseline for the island's morphology in the early 21st century.
