Presumably you came here to learn about Oregon's past, right?

The people who lived here over the last 14,300 years have developed technologies to adapt themselves to the demands of these varied ecological zones with their abundant natural resources.Divide the class into small groups that will each research and orally report on one ancient site uncovered by archaeologists.The goal is for the class as a whole to gain an appreciation for the variations and similarities among ancient cultures and an understanding of scientists' and social scientists' study of ancient cultures.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.
