Riverbluff Cave was discovered accidentally on September 11, 2001, while the county was blasting for a new road on the outskirts of Springfield, MO. In order to protect the pristine, untouched condition of the cave, the county covered the entrance and created and air-tight locked door and passageway system to guard against intruders. The system was completed in April of 2002, and the cave went public later that month. Listen to the NPR spot on All Things Considered from Feb 2007.
Riverbluff Cave is approximately 2000 feet long from main entrance to back room. The heavily decorated main room occupies the first 200 feet of this. Width varies, and there are two side passages that poke out into the nether regions of the cave (one which contains snake remains, and one which is home to the largest congregation of peccary tracks in the world).
Inside Riverbluff Cave is a plethora of findings which have been dated at Pleistocene in age, the time period that spanned from 2.5 million to 11,000 years ago. Items include mammoth bones, horse bones, wolf bones, snake skeletons, turtle shells, fossilized millipedes, numerous small rodent tracks and skeletons, peccary (a type of Ice Age pig) tracks, and numerous bear and large cat claw marks, which show that this cave was used heavily for shelter before it closed so many years ago, waiting to be opened and rediscovered by humans.
Currently our dig team is working in Riverbluff Cave to continue searching for new discoveries. Every time we do one of these digs we uncover something new and answer one more question about our Ice Age past.
