Description

Authors: Crabtree, Don E. (1912-1980)–The Cone Fracture Principle; and Hester, Thomas Roy (1946-)–Ethnographic Evidence

Publisher: Tebiwa (Journal)

Notes: Offprint.  Two photocopied articles from Tebiwa, the Journal of Idaho State University Museum, Volume 15, No. 2, bound in stiff paper boards.  Crabtree was a noted flintknapper and “experimental archaeologist.”  The first article is a technical explanation of the “cone fracture principle” (see photo above).  The second article, by Hester, details the use of heat (and steam) to treat siliceous (i.e. rocks containing silica) rocks prior to flintknapping.  Someone took a lot of time to preserve these two articles.
