About this map

San Jose Island dominates this coastal survey, showcasing a narrow barrier landscape shaped by the Gulf of Mexico and Aransas Bay. In the early 1970s, this stretch of the Texas coast was defined by its transition from tidal waters to stabilizing sand dunes. Notable human presence is centered at the Fairmont Ranch and the small settlement of Joseph, with a dedicated Landing Field providing access to this isolated island terrain.

Functional infrastructure such as a Wildlife Obs Station and scattered resource extraction, including an Oil Well and a Ford, illustrate the land's utility during this era. The complex hydrology of the barrier system is visible through features like Allyns Bight, Allyns Lake, and Long Lake, which segment the island. The survey also captures the relationship between the main island and Mud Island, separated by Blind Pass, reflecting the shifting shoreline of the Texas Gulf Coast.
