Expended Named after points found at the Agate Basin Site in eastern Wyoming. This bison kill contained several points or large and easily identified fragments. They are widest at mid-section with convex edges, narrowing to the base.
Bases are narrow and are relatively straight or slightly concave.
The lower to of the edges are usually well ground. Short Agate Basins are often nubs of larger points that were re-sharpened until the blade was nearly gone. On these points all but the very tip is ground. Numerous examples of Hixton silicified sandstone and non-glossy, tan Cochrane Chert are known from western Wisconsin. A few examples of exotic chert Agate Basin points, including the base of an obsidian specimen from Silver Mound, are also reported for this region.
