An Investigation of Contracting Stem Projectile Points in West-Central Colorado

(2021) Coal Creek Research, Inc.

The purpose of this study is to compare contracting stem projectile points found in west-central Colorado with contracting stem points from the Great Basin by using a cluster analysis approach. Two hundred fifty-two contracting stem projectile points from west-central Colorado are compared with 54 points from three sites in Nevada. The 54 points are from Gypsum Cave, Gatecliff Shelter, and O’Malley Shelter. The study found that the points from Nevada are best represented by four shapes, while those from west-central Colorado are best represented by eight shapes. The points from Nevada did cluster with some west-central Colorado point shapes, but many points from west-central Colorado are not similar to the Nevada points.
