McKean  4,500-3,500 B.P.

McKean is lanceolate in shape, sharp and thin, usually with blade edges incurved toward the tip and tapering toward the base about midway between tip and base.  Occasionally, the sides of the proximal blade-half are parallel.  Usually the base is sharply concave, though sometimes concavity is slight or absent.  The points are lenticular in cross-section and in rare cases show evidence of secondary retouch, grinding, or dulling.  Length range: 1 to 3 inches, width range: .5 to 1 inch, thickness range: .1 to .3 to inch.  Mulloy
