Brumm says this layer of habitation stretches back at least 28,000 years, and he is in the process of analyzing older layers, using radiocarbon dating for the organic remains and uranium series dating of horizontal stalagmites that run through the sediment. Appalachia has a high concentration of these natural voids, including the world's longest. Brumm was working with the late Mike Morwood, co-discoverer of the diminutive homininHomo floresiensis, which once lived on the nearby Indonesian island of Flores.
