About this map

Galveston Island stretches across the southern portion of this survey, serving as the base for several established coastal communities. Developments like Sea Isle, Terramar Beach, and Bay Harbor are characterized by canal-front residential layouts and a dense network of local streets, including San Luis Pass Rd and Kennedy Dr. The map illustrates the specialized infrastructure of this barrier island landscape, featuring the Marina at Sea Isle and the residential fingers reaching into West Bay.

North of the island, the mainland and bay environments reveal a complex system of marshes and tidal waterways. Significant features such as Halls Bayou, Chocolate Bay, and Carancahua Lake define the hydrology of the area. Distinctive landmarks like Rattlesnake Mound and Alligator Point stand out among the various points and islands, including Snake Island and the Bird Islands, providing important reference points for understanding the geography of the Texas Gulf Coast during this period.
