About this map

Avoca Island and the surrounding marshlands of St. Mary and Terrebonne Parishes dominate this mid-century coastal landscape. The terrain is a complex network of wetlands defined by the Intracoastal Waterway and winding natural channels like Bayou Chene, Bayou Black, and Bayou Cocodrie. The 1960s economy of the region is clearly visible through the extensive energy infrastructure, including the North Turtle Bayou Gas Field and a dense network of pipelines that cut across the marsh. Navigation and industry are the primary human imprints here, with the Burke Canal and various drill holes highlighting the extraction activities that transformed the swamp. Waterways such as Turtle Bayou and Bayou Penchant serve as the principal landmarks in a region where solid land is scarce and water dictates the pattern of development.
