Cave Detectives: Unraveling the Mystery of an Ice Age Cave

By: David Harrison

Illustrator: Ashley Mims

"We have to save this cave! You're not going to believe what's down there!" In September 2001, near Springfield, Missouri, a construction company was building a road. They expected to blast away a hill but instead uncovered Riverbluff Cave-one of North America's oldest Ice Age cave sites. Inside are swipe marks from gigantic claws, thousands of hoof prints in still-moist earth, and the fossilized remains of animal feet. Here is the story of how scientists worked to date the cave and identify its treasures. Full-color photos and illustrations. Time line. Glossary.
