AbstractNew results of radiocarbon dating of ca 100 decadal bristlecone pine samples from 6554 to 6084 BC and from 5820 to 5350 BC are presented. Using 3 new 2.5L counters filled to ca 3atm with carbon dioxide, high-precision dating has been performed by this laboratory for more than two years. Demonstration of the precision and accuracy of these counters is presented using +/2 per mil measurements from the Spörer minimum period. For the older samples, +/3 per mil measurements were made using ca 12-day counting times. Results are presented both as 14C age BP vs dendro-year BC, particularly for calibration purposes, and as Delta-14C vs time.
