I wrote a short article for the December 2017 edition of Legacy (Vol. 21, No. 2, available here) about the radiocarbon dates from 38FA608. I wanted to make the dates available (in a way that they can be cited) sooner rather than later. I'll probably wait until after the next season of fieldwork to produce a more formal, peer-reviewed article about the site.
As pointed out by Stuart Fiedel in the comments on my initial blog post about these dates, the date from 38FA608 is apparently only the second radiocarbon date associated with Guilford points. This is despite the fact that the distribution of Guilford stretches from southern Maryland to northern Georgia. Gunn and Foss (1992) reported the first date of 5350 +/- 60 from a Guilford feature at the Copperhead Hollow site (38CT58) in Chesterfield County, South Carolina. The scarcity of Guilford dates presumably reflects the rarity of intact deposits that date to this time period. It is clear that Zone 7 of 38FA608 has the potential to provide significant new information about the late Middle Archaic in the Carolina Piedmont in particular and in the Eastern Woodlands in general.
Season 2 of the field school will be starting up in late January. Watch this space.
