Well this Mid-Columbia area certainly is becoming an outstanding location for anthropologists!
You may or may not be aware that the 9,300 year-old Kennewick Man was found along the Columbia River a few years ago. Well now a lower jawbone was located along the Columbia River last month and it was given to the Army Corps of Engineers because it was found on their land.
Members of the Confederated Tribes of the Umatilla Indian Reservation believe the bones are from a Native American, but an independent anthropologist will study the bones. Intense steps will be taken to resolve any questions as to its origin. The possibility of carbon dating will be considered.
So if you are an amateur anthropologist, you might make the next great discovery right here in your own backyard in Kennewick, Pasco or Richland or along the Columbia River in the surrounding area.
