A little lithic eye-candy for tool-users out there. These are some quick photos I shot while making an examination of some blades for the ongoing tool analysis here at Blackwater Locality 1 (LA3324). Excuse the poor quality of the photos but look forward to seeing them in full all-color glossy glory in the future.
In 1990 a tool cache, including four blades and a large, unifacial flake knife, was unearthed along the western margin of the prehistoric pond on the Clovis site by Joanne Dickenson. Many blades are known from the site and are fairly typical of the Clovis tool-kit, being used as knives, scrapers, and preforms for other tools.
All of these tools were made from extremely high quality Edwards Plateau chert from Texas, although not from the same core. This material hints at the vast distances traveled by early hunter-gatherers on the high plains.
A cache of 5 Clovis artifacts were discovered in 1990 by Joanne Dickenson, curator of the site at that time. The cache consisted of 4 prismatic blades and the large flat flake shown above. All were made from Edwards Plateau Chert. The cache was located along an arroyo or small stream that flowed into the pond from the west during Clovis times (a.k.a. the Mitchell Locality). An earlier blade cache found at Blackwater Draw was excavated by F. Earl Green in 1963 from the North Bank area. The Green blade cache is currently on loan to Dr. Eileen Johnson at Texas Tech University.
