A group of volunteers from a national organization called Earthwatch are in Hot Springs digging up bones.
Cynthia Lewis–Younger came all the way from Tampa, Florida to take part in this excavation.
Cynthia said, "Were here to look for bones in various sites and various kinds, and also we do an awful lot of digging and scrapping to remove sediment."
The technique they are using is they start by spraying down the rocks, getting it wet, using this tool to scrape in a forward motion. They then take sediments and go through it with a brush to check from any fossils they might find.
This job can often be tedious and requires a great deal of patience. Lewis-Younger said, "It takes a long time to excavate something and sometimes you have to work through tough sediments to get there."
Although this job can be grueling, most believe the end result makes it all worthwhile.
Lewis-Younger told us, "Seeing a bone that no human has seen before you, unearthing one, which I did last year, was pretty exciting."
The Mammoth Site has already uncovered 60 mammoths as well as 85 other species of animals, plants and several unidentified insects, however their is still more to be discovered.
Monica Bugbee, the Mammoth Site Perparator said, "In the 70's they did a sample and they drilled down and when they pulled the drill bit back up they had found bone and ivory fragments from at least 40 feet below."
Volunteer crews will be excavating until July 29th in hopes of uncovering more bones.
