Context
Feature 4, hearth in the W block, around which much of the occupational debris was recovered. A large slab lined basin, 69 x 86 cm in dia, 27 cm thick. It was initially encountered ca. 7 cm bmgs. 84 fired slabs and cobbles weighing 26.1 kg were found in the ashy, darkly stained fill. Charcoal chunks were abundant, primarily found under the sandstone slabs lining the hearth. Charcoal was mainly juniper; some pine. 13 flakes were found, plus uncharred goosefoot seeds.
