- Charcoal from Feature 19, initially appeared as a complex of charcoal chunks and small flecks of burned earth and clay, most of which lay within an irregularly-shaped light gray-black ash/charcoal stain. This stain was 1st observed ca. 17 cm below the 1981 ground surface. The stain occupied an irregularly-shaped, asymmetrical basin ca. 50 cm long in profile, with clay chunks in the uppper part of the stain. Small charcoal lenses were found below the clay chunks. Impressions in the clay chunks seemed to imply incorporation into a structure. Fea 19. interpreted to represent only part of a lager phenomenon, the remainder of which either was outside the excavation block or had been destroyed by road construction. Jones, 1986a, gives the date as 3399 +/- 90. This is the author's conversion from the Libby half life to the Cambridge half life. For the sake of consistency within the database, the reader should use the Libby half life, as have I.
