Fort Morgan to the Port of Mobile
Mobile Bay
The whole bay, top to bottom, with a ship channel lit like a runway up its middle.
From Fort Morgan and Dauphin Island the Mobile ship channel runs some thirty miles up the bay, lined on both sides by quick-flashing range and passing lights. Branch channels to Theodore and the rivers split off at composite-group junction lights.
