Family Vacations in South Dakota: Mammoth Site

Courtesy of the Mammoth Site of Hot Springs, SD Inc. The Mammoth Site allows budding paleontologists to experience an actual fossil dig.

This treasure trove of fossils in Hot Springs, South Dakota, was discovered in 1974 when excavation for a housing development unearthed the remains of a woolly mammoth. Since then, budding paleontologists and their parents have visited the site to get hands-on experience in an actual dig.

To date, the fossilized skeletons of 53 mammoths have been identified, along with the remains of a giant short-faced bear, a camel, a llama, a prairie dog, a wolf, fish, and numerous invertebrates. Walkways throughout the excavation afford visitors close-up views of the skulls, ribs, tusks, femurs, and even nearly complete skeletons visible in the mass grave that resulted when these prehistoric animals fell into a sinkhole. Visitors can also see the Ice Age Exhibit Hall, which showcases some of the skeletons alongside a painting or replica of the animal as it would have looked, and they can view a working paleontology laboratory.


A simulated excavation for junior paleontologists is held daily during the summer months. Children learn excavation techniques including how to identify the fossils of different animals. They dig up replicas that are buried in a special area next to the actual sinkhole.

From the roar of prehistoric monsters, to the monster roar of modern machinery -- plan your trip for the right time of the year and you can attend Sturgis, one of the nation's loudest and best motorcycle rallies.
