For the first time in decades, scientists are excavating fossils from an 80-foot-deep cave in North Central Wyoming.
The cave is called “Natural Trap Cave,” because it’s become the final resting place for countless animals in past centuries—including many now-extinct ones like mammoths, short-faced bears, and American lions.
Julie Meachen is a paleontologist at Des Moines University. She’ll rappel into the cave with a team of 15 others.
