P200 Introduction to Prehistoric Archaeology
Site C: Cum'Ahn Site
A very small rockshelter (small, shallow cave) was found situated in the hilly woodland country, overlooking a stream valley. (See sketch of site.) A test trench dug through the shelter revealed a single archaeological layer or "horizon" about 12 inches thick, containing many thin lenses (sub-layers) containing charcoal, animal bones and some flint artifacts. A carbon sample from the base of the layer gave a date of 11,180 + 200 years bp (before present). A carbon sample from the top of the layer gave a date of 10,740 + 150 bp.
Artifacts recovered in the excavation included hundreds of microlithic arrow barbs, many flaked "thumbnail" scrapers out of flint, many flint backed blades, and several deeply worn stone bowls and pounding stones.
The bone refuse consisted mainly of deer bones, including the bones of numbers of young deer fawns.
Flotation samples produced some identifiable plant remains from the site occupation level, including the seeds of some wild berries, a few casings of small roots (corms and bulbs), and many charred shells of pistachio nuts.
