Intrusive Mound Points were first published by William C. Mills in 1922 from his excavations at Mound City in Ross County Ohio. They were found in association with burials made in the tops of existing Hopewell mounds, hence the name Intrusive Mound. The point style has a wide distribution and many regional names but here in western Pennsylvania they are called Raccoon Notched or Intrusive Mound.
There are several variations of this point - all of which are characterized by extreme thinness and delicate chipping. The most common variety is triangular in design with U-shaped side notches. the base is straight and as wide as the shoulders with little to no grinding. The second variety has diagonal corner notches which leave sharp pronounced barbs and stem corners, it sometimes has a pentagonal shape. The rarest variety has a decidedly pentagonal design, the widest part of the point being in the middle of the blade. Also common is the flat tabular blade exhibited in Hopewell points.
Converse postulates dates of 600 AD - 900 AD while Stanley Lantz postulates 500 AD - 950 AD.
Lantz also mentions how many sites that produce Raccoon Notched points in western PA also produce triangular points, I can attest to this. Converse makes no mention of this this.
Below are several pics of these artifacts from my collection.
