We recently submitted samples for radiocarbon dates for Feature 1 at the Karl Site (excavated in 2009 and 2012). The results are in, and the burned rock feature, likely an earth oven, was in use at least 5310 years ago.
It appears the feature was built by a local Lamoka group. They can be recognized in the archaeological record by their short, narrow dart points, like the one pictured below from a Karl Site surface survey.

A report is being produced which will include more details. It will be submitted for publication next spring. We would like to thank our supporting members, and all who were able to contribute toward our Radiocarbon Fund initiative. Thank you for your continued support, as the Bockmier One features will require dating soon. To make a quick contribution in time to include it on your 2014 taxes, you may use our secure donation link on this page (with a credit card or PayPal), or send a check to Allegheny Valley Project, 900 S.
