    So far, this is the only stone artifact found on the Dilts bison kill site. The upper ear in this picture has been digitally restored to give the perspective of its original form. Notice the two parallel oblique flake removals near the point. This spear point is made of fine-grained quartzite and measures 3 1/4 inches (8.2 cm) long.

    What type of point is it and what is its age? We are presently radiocarbon dating a piece of cranial bone in hopes of answering the age question. But answering the other question is much more difficult. Is the point Goshen, Allen, Dalton, Plainview, or perhaps unfluted Clovis? It's difficult to tell. I personally think it is from the late Paleo-Indian Allen complex, which dates between 9,500 to 8,000 radiocarbon years before present from sites on the Central Plains.

DILTS COLLECTION

   This picture shows three views of the single Paleo spear point that was found on the Dilts site in Campbell County, Wyoming. The point is complete except for one ear that was missing. It's made of fine-grained quartzite and measures 3 1/4 inches (8.2 cm) long.

    We all know that single isolated points can be hard to type without any associated dates, other tools, etc. As well, it all depends on where you draw your own experience. I've worked throughout the Central and Southern High Plains and the Paleo-Indian record in those regions is slightly different than that of the northwestern Plains. All sorts of things can cause variability in lithic technology, including the raw material availability and quality, the functions of the tools at hand (knives verses points), and of course, the group of people making the points. We simple don't know if point types always equal cultural groups during the Paleo-Indian period. I have my doubts that we'll ever be able to figure that out. But one thing is for certain, this form of lanceolate, concave based projectile point was one heck of an important design, because folks used it all over North America at the end of the Ice Age and for the next several thousand years. The point form even reappears during the Plains Archaic, as the McKean point is a smaller version of this same design.

BISON SACRUM BONE

DILTS COLLECTION

    Close-up of a buried bison sacrum that was found eroding from the side of the hill on the Dilts site.

    We hope to return to the Dilts bison kill sometime in the near future and excavate a small portion of the site to determine whether there are any more bones or tools buried on the site. Hopefully the site will be protected and preserved so that additional information can be added to the continuing story of Paleo-Indians on the high Plains of Wyoming. Thanks to the landowner and the energy company for allowing our work on this site. If you have any questions or comments, please email me at jlabelle@westernls.com
