Context
Charcoal from Feature 127, a rock-filled, basin-shaped hearth; 1 of 5 probable hearths within a 2-m sq area (X42). Meas slightly more than 60 cm in dia., 26 cm deep below the eroded ground surface. Steep-sided, unlined. No oxidation observed and only a small number of quartzite flakes in the fill. NOTE: a date of 6036 +/-90 is given in text. This date is the authors conversion from the Libby half life to the Cambridge half life. The reader should use the Libby half life, as I have, for the sake of consistency within the database.
