2015 Map of Mitchell Island

About this map

Mitchell Island and the surrounding marshlands of Saint Bernard Parish dominate this coastal survey, where the Louisiana landscape dissolves into the Gulf of Mexico. The area is defined by a complex network of estuarine features, including Cranetown Bay and Drum Bay, illustrating the fragile state of the outer delta. Small landmasses such as Martin Island and Turtle Pen Isle stand as remnants of the shifting coastal geography, separated by narrow navigable channels like Keelboat Pass and Elephant Point Pass. This 2015 study by the U.S. Geological Survey provides a precise view of the hydrography of Chandeleur Sound, tracing the intricate curves of Redfish Bend and the sheltered waters of Conkey Cove. The absence of roads or permanent structures reflects the maritime nature of this wilderness at the edge of the Mississippi River delta system.
