María Elena saltpetre works. The María Elena nitrate plant is the last nitrate works still in operation in the world. It was initially named Coya Norte, but was renamed María Elena (after his wife Mary Ellen Condon) [1] by its founder Elias Anton Cappelen Smith.
The cave was used since before 1835 as a source for nitre (saltpeter) for the manufacture of gunpowder. During the American Civil War, Confederate soldiers under the command of General Robert E. Lee again mined the cave for nitre. The cave today has the nation's largest collection of Civil War-era saltpeter hoppers.
