1933 Map of Bolivar Point

About this map

Galveston Bay dominates this coastal survey, where the deep waters of the Gulf meet the intricate shoals and reefs of the Texas shoreline. The 1930s maritime landscape is defined by the elongated Bolivar Peninsula and the strategic position of Bolivar Point at its tip. A notable engineering feature is the Texas City Dike, stretching into the bay from the west to manage siltation and currents. This map reveals the underwater topography essential for navigation during the era, including the expansive Hannah Reef and the isolated Hannah Island. Compiled in part from early Air Corps aerial photography, the map provides a precise look at the shoreline before mid-century coastal development, documenting natural landmarks like Baffle Point and the early alignment of State Route 87.
