About this map

Galveston and its easternmost coastal reaches are defined by the critical maritime infrastructure that connects the Texas mainland to the deep waters of the Gulf of America. This 2025 survey details the eastern tip of Galveston Island, including the sand and marsh of Big Reef and the recreational stretch of East Beach. The geography here is dominated by deep-water transit, with the Houston/Galveston Navigation Channel and the Galveston Bay Entrance Channel serving as the primary arteries for international shipping.

The northern edge of the map shows the tip of the Bolivar Peninsula across the opening of Bolivar Roads. This area is a landscape of shifting sands and engineered stability, where roads like Apffel Park Rd and Boddeker Rd provide land access to the very edge of the shipping lanes. The map captures the specialized hydrology of the Inner Bar Channel and Outer Bar Channel, essential for understanding the modern shoreline of this historic port city.
