To be trapped in asphalt is a terrible way to die but a wonderful way to preserve fossils! The literally millions of fossils recovered from the sticky seeps of the world's richest Ice Age fossil site document what life was like in California when the first humans arrived here. A hundred years of excavation has revealed who was living here, what the local habitats were like, the changes that took place in response to global cooling and warming, and hints at why we no longer encounter sabertooths and mammoths.
