1983 Map of Anahuac

Navigation and transport are central to the area's development, evidenced by the Intracoastal Waterway and various railroad lines including the Southern Pacific and Missouri Pacific. Coastal settlements like High Island and Gilchrist sit along the Bolivar Peninsula, while inland communities such as Hamshire and Hankamer serve the surrounding agricultural and oil interests. The map provides a precise record of the shoreline and drainage patterns through Trinity Bay and East Bay before later modern developments altered the local topography.
