When excavated, this cave contained eight different layers. (see sketch of stratigraphic profiles) Carbon-14 dates on charcoal from the layers produced the following chronology:
Table A-1 |
||
Layer |
Description |
C-14 dates years BP (before present) |
Layer 1 (top) |
15 cm layer of disturbed sediments, including artifacts from recent historical periods, with sterile rubble at the base |
400 + 100 BP |
Layer 2 |
10 cm layer of undisturbed sediments under the rubble, rich in organic remains and stone features |
570 + 100 BP |
Layer 3 |
10 cm layer, including charcoal blown into the site from forest fires is common in the sediments of this level |
630 + 100 BP |
Layer 4 |
10 cm layer |
710 + 200 BP (from top of this layer) 800 + 100 BP (from base of layer) |
Layer 5 |
15 cm layer |
1,200 + 150 BP (middle of layer) |
Layer 6 |
20 cm layer |
1,850 + 100 BP (top of layer) |
Layer 7 |
20 cm layer with evidence of canine burial |
2,360 + 100 BP (top of layer) |
Layer 8 |
30 cm thick layer, with undifferentiated sandy sediments and low density of artifacts |
3,300 + 200 BP (from top of layer) 3,500 + 300 BP (from base of layer) |
Table A-2 below shows approximate frequencies of the artifact types found in the different layers. Note how the frequencies change through time.
· type 1 = flaked stone adze
· type 2 = chert blades
· type 3 = S. gigas chipped adze
· type 4 = S. gigas ground adze
· type 5 = Codakia sp. scraper
· type 6 = expedient shell tool (unknown species)
· type 7 = ceramic griddle
· type 8 = spinning whorl
· type 9 = obsidian
· type 10 = bone fishhooks
· type 11 = bone awls
· type 12 = beads made from S. gigas shells
· type 13 = ceramic adornos
· type 14 = Saladoid ‘zic-ware’ pottery
· type 15 = Troumassoid pottery
· type 16 = Suazoid pottery
[blank = absent; X=present, but rare; XX=common; XXX=abundant)
