Organ Cave

Significant fossil discoveries bear witness to the early natural history of Organ Cave: giant ground sloth, grizzly bear, nine-banded armadillo, sabre-tooth cat, reindeer and an Ice Age porcupine. Organ Cave's human history is attested by flint arrowheads used by early Native Americans. Evidence of early white settlers in the cave is suggested by the date "1704" scratched on a wall, but this may be a later addition since the first white settlers to Greenbrier County came only in the 1740s. 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. Studies have shown the cave dirt is high in calcium nitrate, which was turned into potassium nitrate using these hoppers. Organ Cave was first surveyed by members of the National Speleological Society in July 1948. For many years it was considered the longest cave in the world. , the Organ Cave System had of surveyed cave passage making it the 55th longest cave in the world, the 16th longest in the United States, and the 3rd longest in West Virginia. ==Jefferson's ground sloth==

" rather than Jefferson's giant ground sloth.) Formerly, a famous fossil discovery—that of Thomas Jefferson's giant ground sloth (Megalonyx jeffersonii)—had been assumed to have come originally from Organ Cave. Jefferson never visited the area, but received the fossil from a local friend in 1796. In the early 20th century, a local man, Andrew Price of Marlinton, decided that the fossil had come from Organ Cave and popularized his theory. In 1995, however, Smithsonian paleontologist Frederick Grady proposed that Haynes Cave in nearby Monroe County was the true source. (His reasons had to do with historical land-ownership records.) In 2008, the governor of West Virginia held a ceremony at Organ Cave to present the owner with a certificate stating that M. jeffersoni was the "Official West Virginia State Fossil" and repeated the assertion that it was indeed found in Organ Cave, but without producing any new evidence. ==See also==
