First Look Inside the Fossil Cave

Go inside the cave system where researchers have been working to retrieve ancient hominid bones. Steve Tucker and Rick Hunter are the cavers who spotted the remains initially. The two friends were out exploring for fun a few weeks ago, when they squeezed down a 20-meter vertical crack and saw bones—the kinds of fossils local paleoanthropologist and National Geographic Explorer-in-Residence Lee Berger had asked their caving club to keep an eye out for.
