This unbroken authentic example was sent in for casting in 2011.  It is a Calf Creek from the Early Archaic(around 8,500 to 9,500 B.P.) and it measures 2 and 3/4" long and 1 and 7/8ths inches wide.  It is made in tan chert, and is considered to be an example of one of the most finely flaked types in the Americas.  Calf Creeks are famous for their extremely long notches, and it is extremely rare to find one with the tangs unbroken by history.  There is still much debate whether these types are too fine to be used as projectile points, or whether they were just used as knives.  There is archaeological evidence of both uses, and all agree it is one of the most skillfully made point types in the world.  (COA Stermer 2010
