Join in the hunt for mammoth fossils in South Dakota as a member of the longest-running Earthwatch Expedition.
When a construction crew bulldozed over land in Hot Springs, South Dakota, in 1974, they were stunned to find a mass gravesite for Columbian mammoths, a species that lived in North America until about 11,000 years ago. Dr. Larry Agenbroad stepped in to investigate. In 1975, Dr. Agenbroad and his team found a complete skull of a mammoth, including tusks; in 1976, Dr. Agenbroad teamed up with Earthwatch to launch what is now the longest-running Earthwatch project. The site is now the largest repository of Columbian mammoths in North America, and 60 complete mammoth skeletons—including three woolly mammoths—have been unearthed to date.
Today, Earthwatch volunteers continue to uncover amazing remains from ancient times. In addition to trowels and brushes, volunteers now use high-tech equipment such as CT scans, global positioning system (GPS), and computer mapping technology. As a member of the Agenbroad team, you may unearth remains of creatures ranging from the Columbian mammoth to prairie dogs, camels, llamas, bears, and pronghorn antelopes. Whatever your discoveries, they will add to the wealth of knowledge still emerging from this extraordinary dig.
