This large map was produced as part of a plan to improve the entrance to the Mississippi River related to silt causing problems with navigation. This is graphically depicted on the map with two engraved vignettes; S.S.W. View of Mud Lump, the Wart, and S. View of Carr's Lump., which are small islands marked with makeshift markers to alert ships to navigational hazards. The chart locates Oyster Bay, Bay Ronde, and Garden Island Bay. Also shows Steere's Reef, the South and North East lighthouses, numerous bayous, and much more. The map is attached to the original 4pp report related to Senate bill 342 for "making an appropriation for continuing the operation of deepening the channel at the mouth of the Mississippi river."

Condition: A

The map is in extraordinary condition for a folding map of this size. Clean and bright with no flaws save for a very small piece of the paper at lower neatline is attached to binding, torn off when map was first opened. The disbound report is very good.
