Feature 5, a "hearth" that likely functioned as the heating element of an earth oven built around 600 B.C. (2,600 years ago) during the latter part of the Middle Archaic according to the prevaling chronology of the region. Charred wood from the feature was dated to 2450 +/- 60 radiocarbon years, which when calibrated is approximately 580-600 B.C. (An earlier calibration method was used in 1986, yielding a slighly younger estimated date of 480 B.C.) |
