About this map

Old Fort Beauregard Ruins stand as a historical marker along the edge of Lake Borgne, anchoring a landscape defined by the intersection of natural bayous and massive mid-century civil engineering. The dominant feature is the Mississippi River-Gulf Outlet, a deep-draft shipping channel cutting through the marshlands and flanked by extensive spoil areas. This industrial artery drastically altered the hydrology surrounding established fishing and trapping communities like Yscloskey, Alluvial City, and Shell Beach.

The eastern portion of the map is preserved within the Biloxi State Wild Life Management Area, where a dense network of water bodies including Petes Lagoon, Muscle Bay, and Bayou Biloxi persist. Evidence of resource extraction is visible at the Bayou Biloxi Gas Field and several scattered drill holes. Notable coastal landmarks such as Pte aux Marchettes and the elevation of Magnolia Mound provide critical points of reference in this coastal environment.
