- Context
- Charcoal from Feature 9, an irregularly-shaped oval charcoal filled Feature with a max dimension of ca 2 m. It lay adjacent to several large sandstone boulders. Excavation revealed that the F9 fill lay within a shallow depression whose outline was incomplete (erosion and road construction destruction). It had a smooth, rolling floor, pitching S and E. Boundary with lower sediments was distinct. A number of interior features were within F9. F8, a rock-filled, partially slab-lined hearth near the N edge. the top of Fi was exposed at 42-65 cm below the 1981 surface. Meas 60 cm in dia, with steep sides. N half lined with small cobbles. Fill contained charcoal, burned bone, and a small amt of quartzite debitage. A metate also found in F9. The dated sample is from F9 rather than the smaller F8 within Fl. Jones hesitated to call this feature a structure, noting that the metate and the slab-lined hearth found in F9 lay within the charcoal-stained soil matrix of the feature, clearly above the lower limits of the stain. Jones reports the date as 3698 +/- 60. 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.
