About this map

Galveston Island defines the coastal landscape of this 1963 survey, revealing the early development of Sea Isle and Bay Harbor along the Gulf of Mexico. The map illustrates a transitional period for the Texas coast, where recreational and residential expansion met the established industrial path of the Intracoastal Waterway. To the west, the winding course of Halls Bayou flows past the Fishing Cabins and Rattlesnake Mound before entering the expansive Halls Lake.

The hydrographic data, compiled in part from 1964 charts, highlights the complex network of shoals and points such as Carancahua Point and Alligator Point. The boundary between Galveston and Brazoria counties cuts through the waters of West Bay, marking the administrative divide across this environment of marshes and bays. This map is particularly useful for observing the footprint of San Luis Pass Road and the surrounding shoreline before later decades of intensified coastal development.
