2016 Map of High Island

About this map

Bolivar Peninsula projects into the Gulf of Mexico on this survey, highlighting a coastal landscape defined by salt marshes and intricate bayous. The settlement of High Island sits atop a rare topographic rise, surrounded by low-lying wetlands including Horseshoe Marsh and the Lower Marsh. This area is characterized by the engineered path of the Intracoastal Waterway, which cuts through the native drainages of East Bay Bayou and Mud Bayou. Along the coastline, the community of Gilchrist marks the narrow strip of land between the Gulf and East Bay. Local landmarks like Smith Springs and Knoll Ponds suggest the delicate balance of fresh and salt water across this coastal prairie. The map provides a clear view of the road networks serving these communities, from Audubon Ave to the numerous local routes like Oilfield Rd and Old Hwy 87.
