We discuss the analysis of 39 Oxidizable Carbon Ratio (OCR) dates obtained from the Late Caddoan Morse Mounds site (41SY27), in the far eastern part of the state of Texas. This is one of the largest OCR dating studies completed in Northeast Texas. We also considered how soils behave as living, open systems and provide a brief introduction to the OCR Carbon Dating procedure. Data from close-interval sampling of the soil column describe the soil's physiology and provide a spatial and temporal context for evaluating the accuracy of the OCR Carbon Dating procedure in independently establishing the age of this archeological site.
