Marveling at the salt process lures few visitors to Inagua, but the Morton Salt Company is omnipresent on the island: it has more than 47 square mi of crystallizing ponds and reservoirs. More than a million tons of salt are produced every year for such industrial uses as salting icy streets. (More is produced when the northeastern United States has a bad winter.) Even if you decide not to tour the facility, you can see the mountains of salt, locally called the Salt Alps, glistening in the sun from the plane. In an unusual case of industry assisting its environment, the crystallizers provide a feeding ground for the flamingos. As the water evaporates, the concentration of brine shrimp in the ponds increases, and the flamingos feed on these animals. Free tours are available by reservation at the salt plant in Matthew Town.
