Around 11,000 years ago, a Paleoindian culture known to us as "Clovis" occupied much of North America. Considered to be among the continent's earliest human inhabitants, the Clovis peoples were probably nomadic hunters and gatherers whose remaining traces include camp sites and caches of goods stored for utilitarian or ritual purposes. This book offers the first comprehensive study of a little-known aspect of Clovis culture—stone blade technology. Michael Collins introduces the topic with a close look at the nature of blades and the techniques of their manufacture, followed by a discussion of the full spectrum of Clovis lithic technology and how blade production relates to the production of other stone tools. He then provides a full report of the discovery and examination of fourteen blades found in 1988 in the Keven Davis Cache in Navarro County, Texas. Collins also presents a comparative study of known and presumed Clovis blades from many sites, discusses the Clovis peoples' caching practices, and considers what lithic technology and caching behavior can add to our knowledge of Clovis lifeways. These findings will be important reading for both specialists and amateurs who are piecing together the puzzle of the peopling of the Americas, since the manufacture of blades is a trait that Clovis peoples shared with the Upper Paleolithic peoples in Europe and northern Asia.
