Context
wood from Hearth B3, a stone filled, circular basin dug from the contact between Units 4 and 5; meas. 41 x 45 cm in dia., 7 cm deep. Floor thermally oxidized in a thin zone. Fill: 11 stones, 4 - 14 cm in max. dia., set in a matrix of relatively pure charcoal. Eight of the stones were oxidized. A rim of earth present on the E side of the basin, probably the result of earth pushed to the side in cleaning the feature for re-use. No artifacts assoc. with the fill. Lithic Workshop E, containing cryptocrystalline quartzite flakes derived from resharpening of butchering tools was centered on Hearths B-3 and B-4, but could not be specifically related to either.
