They found a skull. Dude!! Police were called. One of our church members was called (anthropologist) to ID that this skull was really, really old. His daughter, one of the Sunday school tribe and artist, drew the first representation of the skull. Report and original drawing here.
Kennewick Man went on to all sorts of adventures. His whole skeleton was dug up. Lots of people put in claims for kinship. My personal favorite was the Druids.
He has been studied ever since.
Now he has a new book coming out which I have already pre-ordered.
