heat treated chert

This is a Hamilton point based on the basal thinning flake on the points stem.
Hamilton points consistently have basal thinning of the stem area, usually on both sides. That
thinning can be one or two or three thinning flakes that pretty much extend the length of the stem.
The chert is heat treated and has turned shades of pink and red due to heat treating and an iron
content in the chert itself. From the Middle Archaic (~7,500 to 4,000 yrs BP) onward, heat treating
of chert became common as a means to make it flake better.
