About this map

Galveston Island serves as a focal point for this coastal survey, where the barrier island's southwest reaches meet the expansive waters of West Bay. The landscape is defined by the tension between the developed beachfront communities and the sprawling marshlands of the Gulf of Mexico coastline. Established settlements like Sea Isle, Terramar Beach, and Bay Harbor show a dense network of residential streets such as San Jacinto Dr and Isla Del Sol, positioned just behind the protective stretch of West Beach.

Directly across the Intracoastal Waterway, the topography shifts toward the wilder terrain of the mainland, marked by the winding paths of Halls Bayou and Cow Bayou. This area is punctuated by landmarks of interest to local historians and coastal researchers, including Rattlesnake Mound and the distinct shoreline features of Alligator Point and The Narrows. The map meticulously charts the shifting sands and shallow habitats of Bird Islands and Snake Island, illustrating the complex estuarine environment where Chocolate Bay opens into the larger bay system.
