- Context
- Feature 6, a slab-lined roasting pit revealed during testing. Meas. ca 88 x 95 cm in dia.; 60 cm deep. Large sandstone slabs lined the sides and bottom of the pit excavared into the shale substrate. Slabs were burned, witha 1-2 cm thick layer of oxidation surrounding the area beyond the slabs. indicating an intense fire. Fill: primary ash and charcoal, but 2 distinct strata. Upper layer was mixed shale and loam with small pieces of charcoal. Below this was 40 cm of dark brown clay loam with a lot of charcoal, daub, and FCR. Artifacts in fill: 11 flakes (one was an obsidian flake), 1 core). No Zea mays pollen. The daub was later interpreted as part of an adobe cover that had collapsed. The amt of daub indicated a dome cover, and individual coils were seen.
