Ground Stone Technologies Workshop

August 22, 2019 @ 8:00 am - August 23, 2019 @ 5:00 pm

Instructor: John L. Fagan, Terry L. Ozbun, Kelley Prince Martinez

This two-day workshop emphasizes hands-on production and analysis of a series of ground stone reduction technologies. Ground stone technologies covered in the workshop include mortar and pestle, mano and metate, net weights, slate points, and abraders. Reduction methods include flaking (for initial shaping), pecking and grinding. Instruction emphasizes the comparative analog power of modern experimental tool replication to explore ancient raw material selection, reduction strategies, and use wear attributes. The course will teach the principles of ground stone analysis through the identification of characteristic manufacture and use wear attributes, along with archaeological applications of technological analysis for understanding reduction strategies and the use-life histories of ground stone tools. Additionally, participants will produce their own comparative ground stone tool collection. This program enhances an archaeologist’s ability to meet the RPA code of conduct and its standards of research performance through acquiring additional expertise and methodologies to interpret the archaeological record and understand past cultures and behavioral patterns. These ground stone technology analysis methods are needed in archaeology to inform on regional Indigenous raw material knowledge, resource use, and tool manufacturing and maintenance practices.
