Finely executed French Service Hydrograhique de la Marine chart no.4710, showing the Mississippi Delta from Mobile Bay to New Orleans.

The map extends from Lake Ponchartrain and La Maurepas in the northwest to Mobile Bay and the outer barrier islands, with the Delta extending to the south . Dozens of lighthouses re shown.

The map is based upon the maps and charts of the United Coast Survey.

Includes two inset maps:

  • Passe de l'Ile Horn
  • Passe du Sud. 


The chart is very rare.  We note one example at auction (this copy) in the past 30 years.

No examples listed in OCLC.  We were unable to locate any other examples of the map.
