About this map

Jones Island and the surrounding marshlands dominate this 1968 topographic survey, illustrating the complex hydrology where the Tangipahoa River meets Lake Pontchartrain. The landscape is defined by an intricate network of natural and man-made waterways, including Pass Manchac, North Pass, and numerous industrial or drainage cuts like Fuller Canal and Schleiders Ditch.

Evidence of historical land use and early habitation appears with the notation of Indian Mounds near the shoreline and a Flowing Well further inland. These features, along with the varying character of Mays Bayou and Stinking Bayou, reveal how human activity has long interacted with the wetlands of the Tangipahoa Parish and St. John the Baptist Parish boundary. The map provides a precise record of the shoreline and swamp depths before later 20th-century developments further altered the coastal environment.
