About this map

Lonesome Island and Belle Isle stand as prominent landmarks in this saltwater marsh landscape of coastal Louisiana. This marine-dominated environment is defined by a complex network of named channels and bays, including Black Bay, California Bay, and the interestingly named Whiskey Bay. These features reveal a coastal topography shaped by tidal flows and historical navigation, where small rises in elevation like Stone Island provide the only breaks in the open water.

Navigational landmarks such as Telegraph Point and Curfew Point anchor the eastern side of the quadrangle, while a series of interconnected passages like Bel Pass and Bel Pass Bayou facilitate movement through the wetlands. The absence of roads or permanent settlements emphasizes the role of water-based transit in this part of Plaquemines Parish, where Bay Gardene and Bayou Lost represent the intricate inlets that have long served local fishermen and mariners.
