Kennewick Man mystery

Kennewick Man
Kennewick Man is the name for the skeletal remains of a prehistoric man found on a bank of the Columbia River near Kennewick, Washington, USA on July 28, 1996. The discovery of Kennewick Man was accidental: a pair of spectators (Will Thomas and David Deacy) found his skull while attending the annual hydroplane races.The remains were first examined in situ by anthropologist James Chatters. After ten separate visits, Chatters was able to collect three hundred and fifty pieces of bone as well as the skull, which completed almost a full skeleton.The cranium was fully intact except for two teeth. All of the major bones were found although in several pieces.At the University of California at Riverside, a small piece of bone was subjected to radiocarbon dating. Unexpected test results showed that the remains were approximately 9,300 years old, rather than from the nineteenth century, as had originally been assumed.After collecting all the bone pieces, Chatters concluded the subject was a Caucasoid male about 68 inches (173 cm) tall who died in his mid fifties.Chatters found the bone had partially grown around a 79 mm (3.1 in) stone projectile lodged in the illium, part of the pelvic bone.On x-ray, nothing appeared. Chatters put the bone through a CPT scan, and it was discovered that the projectile was made from a siliceous gray stone that was found to have igneous origins.Geologically, this refers to a stone that formed in a silica-rich environment during a volcanic period. The projectile was leaf-shaped, long, broad and had serrated edges, all fitting the definition of a Cascade point. This type of point is a feature of the Cascade phase, occurring in the archaeological record from roughly 5000 and 8000 years ago. -Wikipedia-
