Jack's Reef pentagonal projectile point
Jack's Reef pentagonal projectile points are stone projectile points manufactured by Native Americans what is now the northeastern United States generally in the time interval of 600-1200. They derive their name from the specimens found at the Jack's Reef site in Onondaga County, New York.
Jack's Reef pentagonal points are generally about 1 to 1 3⁄4 inches long. They are generally rather thin and pentangular in shape, about one and a third times longer than they are wide. They usually have a straight base. They are generally made from local flints, jasper, quartz and quartzite.
Age and cultural affiliations
These points are generally found in the American northeast (New York, Ohio, Pennsylvania, Virginia).
