Eleven Jones Cave
Encyclopedia
Eleven Jones Cave is located by Beargrass Creek
in Louisville, Kentucky
. It is 1600 feet (487.7 m) southeast of the corner of Eastern Parkway and Poplar Level Road on the west bank, between Louisville Cemetery and Calvary Cemetery, near St. X High School. It is developed in Louisville Limestone
448 feet above sea level. A spring discharges water into Beargrass Creek.
The cave is the best known and best documented in Jefferson County
. It is popularly said to be named for being used by eleven brothers named Jones; however, some believe it was actually named from early residents Levin Powell and John Jones.
The stoopway entrance that is 4.5 feet (1.4 m) high and 2.5 foot (0.762 m) wide leads to a forty foot passage into a fairly normal limestone
crawlway conduit cave. It is the only known habitat for Louisville cave beetles, that is listed as a Candidate for endangered species status.
Three-inch bars on a gate were supposed to further decrease the chances that someone might find Jones' gold, silver, and jewels. These bars were said to prevent access to a main passage, which was also supposed to be guarded by a cannon. A book published by University of Kentucky Press has called this account "mythical".
Early descriptions of the area, as late as 1822, make no mention of the cave or legends surrounding it, but it was known to locals as the source of a spring by 1831. It was first definitively called Eleven Jones Cave in 1848. Eight entrances were said to have been located along Beargrass Creek, although none but the main entrance were ever found.
was found within the cave. All it found was that the cave had no entrance other than the reliable spring entrance on Beargrass Creek.
"Bad air" is present in the cave, with very high levels of carbon dioxide
just inside the entrance. Dangerous hypoxia is possible within minutes, and fatal poisoning is likely farther into the cave. Concentrations of CO2 inside the cave are in excess of 10 times the normal atmospheric value.
It is the only known location for living Louisville cave beetles, Pseudanophthalmus troglodytes. This insect is reddish-brown, small, eyeless, and eats invertebrates. The Louisville cave beetle was described in
1973 from specimens collected from Oxmoor Cave (near Oxmoor Center
). During 1994, surveys of other caves that could potentially support the species were conducted and the species was found in only one additional cave: Eleven Jones Cave. Oxmoor Cave was bulldozed over in 1990. It has been listed as "imperiled" by the Kentucky Natural Heritage Program. Since 1994 it has been a candidate for ESA protection, but currently has no state or federal protections.

The legend
The Jones were supposed to have used the cave as a hideout in the 1800s. They were reportedly bank robbers, counterfeiters, and murderers. They stashed their ill-gotten gains within the cave. The brothers also created eleven rooms to live in within the cave. The Jones eventually left the area, and their treasure reportedly hid behind collapsed rocks. Since the rooms have never been found, legend often says the gang sealed them off by collapsing the cave roof. The cave was supposedly once large enough to drive a horse and carriage through, but has since "shrunk," a geological impossibility.Three-inch bars on a gate were supposed to further decrease the chances that someone might find Jones' gold, silver, and jewels. These bars were said to prevent access to a main passage, which was also supposed to be guarded by a cannon. A book published by University of Kentucky Press has called this account "mythical".
