1933 Map of San Luis Pass

About this map

Galveston Island and its southwestern tip are the primary focus of this maritime survey, illustrating the dynamic coastal landscape of the Texas Gulf Coast as it appeared in the early 1930s. The map captures the narrow, undeveloped spit of land guarded by the San Luis Coast Guard station, a vital landmark for navigation and safety along this exposed stretch of shoreline. The boundary between Brazoria Co and Galveston Co bisects the treacherous waters of San Luis Pass, a natural break separating the main island from San Luis Island. This era of the coast is documented prior to significant modern development, showing the shifting sands and salt marshes that define the interface between West Bay and the open Gulf of Mexico. The survey provides a clear view of the natural hydrology and coastal defenses of the region during the interwar period.
