In July, a small feature at Pig Point (18AN50) was excavated. This feature, now known as Feature 178, was found intruding into Stratum 12 in Unit 70. It was found to contain ash and charcoal. The charcoal was sent to a lab to be carbon dated and we recently received the results. The charcoal dates back to BC 7340 - 7070, over 9000 years ago! This dates this feature back to the Early Archaic.
Radiocarbon dating is a technique utilized by many archaeologists. This technique involves measuring the loss of the isotope Carbon-14. This isotope accumulates during the life of organisms. At death, the isotope will decay at a constant rate; in which the half life is 5730 years. By measuring the amount of the isotope left within the organism, the age of the organism can be found.
