Description :
A sequence of radiocarbon-dated buried trees, buried soils, a carbonate zone and a molluscan fauna from Carnegie Canyon indicate that between 3 200 and 2 600 yr B. P. the climate of West Central Oklahoma was drier than today. A high water table accompanied a period of moister climate 2000 to 1000 yr B.P. The water table dropped after 1000 yr B.P. due to a change toward dry conditions.
