Amos Corner Notch
Cluster: Kirk Corner Notch Cluster Description of Physical Characteristics and Flaking Pattern:
This is a small to medium triangular corner notch point with an elliptical cross section. The blade is primarily straight and deeply serrated with a needle like tip. Serrations are formed using oblique flakes, but do not run to the center of the blade and do not form a median ridge. The tip may be off center, usually seen on re-sharpened examples. Re-sharpened examples may have finer serrations. Deep corner notches form shoulders that are barbed with one shoulder commonly being longer than the other with an expanding stem. The base ranges from 1/2 to 2/3 the width of the shoulder, but never the same width. The base may vary from straight to convex with basal thinning by the removal of 2 or 3 little flakes with light basal grinding present. Basal corners are sharp, but rounded of with a few small flakes. This point has a high quality of workmanship and has a random flaking pattern.

Additional Comments:
Bob Byard, a local avocational archaeologist, noted that this point is often confused with a Palmer type. This may be due to Betty Broyles's speculated that Amos points would be found below the Kirk Horizon if excavations at the St. Albans site had proceeded further . Matthew Smith notes that no publications or excavations where Amos points have been found have every reached the Kirk Horizon. All RC data point to a post Kirk Horizon.

Age Details:
Type site 46Pu60 (John E Amos Power Plant site) yielded three radiocarbon dates between 6,300 and 7,750 RCBP. The earliest date had a margin of error +/- 450Y, the other two averaging 6,500 RCBP +/- 100Y. The Charleston Town Center (46Ka165) yielded a date of 6,635 RCBP +/- 110Y. In the lower Allegheny valley, 36Ar188 yielded a date of 4,570 BC +/- 160Y.
