The Calf Creek is one of the most skillfully made points in all of the world, made famous by its deep and delicate notches.  The associated culture ranged throughout the American Midwest, going as far east as Tennessee.  An idea of the time period for this point was given in 2003 when a Calf Creek point was found imbedded in a bison skull on the edge of the Arkansas River, OK .  The skull was dated to around 5,000 years ago, although many of the point type books had these listed as old as 8 to 9,000 years ago.  This find also showed that the type could well be used as a projectile point.  It was previously thought by many that the style was too delicate, wide, and flat for projectile use and was probably used as a knife.  
 
The material for these points is usually cherts whose source is in the Ozarks, and this example was made in black Pitkin chert.   Due to the extra long notching, it is rare to have a Calf Creek survive with both barbs intact as this one has.  This point was loaned from a private collection in Ohio, and sent to Occpaleo for casting in 2011.
It is from White County, Arkansas and measures 2 inches in length.
