- Context
- Feature 8, a slab lined hearth, 3m2 m from Feature 2. It was circular, 88 x 90 cm, basin shaped, exposing a 30 cm diameter area of sandstone bedrock. Lower fill was dense ash 2-8 cm thick. Embedded into the top of the as were 170 pieces of charcoal stained tabular sandstone; mostly flat and abutting each other. They weighed 24.9 kg. The upper basin contained dense black charcoal; only light oxidation on some of the sandstone slabs. One piece of debitage and juniper charcoal in the fill. Multiple episodes of use are thought to be evidenced, and the slab lining is thought to be common in Archaic hearths.
