1855 June 1. Light discontinued.
1879 Southwest Pass of Vermillion Bay, Louisiana.Some years ago a light stood on Marsh Island, to mark the entrance through this pass into Vermillion Bay, but was destroyed. The importance of this pass has lately been brought into prominence, through the development of the salt mines on Petit Anse Island, the pass being the nearest outlet for the product of the mines. This pass also affords an anchorage in heavy weather for light-draught vessels plying on the Gulf coast. A light at this point would also tend to illuminate a dark space on the coast between Southwest Reef and Calcasieu light-stations, a distance of some one hundred miles without a light.
