Instructor: Robert L. Bettinger, Distinguished Professor Emeritus, UC Davis

This workshop will introduce the theoretical foundation of foraging theory, beginning with the concept of rational choice and definition of costs and benefits. Explores application of the foraging models most amenable to application to the archaeological and ethnographic record. Participants may sign up for morning and afternoon, morning only, or afternoon only. You must have a PC to obtain full benefit. Working knowledge of Microsoft Excel highly useful. Preregistration is Required.

ROCK1: Rock Art Conservation Management for Site Stewards and Managers
Instructor: Jeremy Freeman

March 4, 2021, 8:00 a.m. – 12:00 p.m. Cost: $35.00

Rock art is a resource that captures people’s attention and provides a way for modern people to relate to ancient people. However, it is also one of the most sensitive resources due to its high visibility and changing climatic conditions that threaten the stability, integrity, and aesthetic quality of the sites. In this workshop participants will learn how to identify the transformational processes affecting rock art sites. Participants will learn how to complete a condition assessment form and collect conservation management data that will provide a better understanding of the conservation needs of a rock art site. Participants will learn about preparing a conservation management plan along with intervention procedures used by professionals to help conserve rock art sites. Participants will, additionally, learn about methods used to collect conservation management data and how it can be used to make better-informed decisions by site managers. Preregistration is Required.

ROCK2: Using 21st Century Technology for Non-intrusive Rock Art Documentation
Instructor: Jeremy Freeman

March 4, 2021, 1:00 p.m. – 3:00 p.m. Cost: $25.00

Advances in technology have resulted in a metamorphosis in archaeological methods with an increasing emphasis on non-invasive, non-destructive techniques. Modern technology is allowing researchers to adapt of new analytical methods without compromising the integrity the archaeological evidence. This is particularly true in rock art research that has experienced an increased push for non-intrusive documentation. In this workshop participants will learn about some of the technologies available to researchers to document rock art non-destructively using modern technology. Participants will learn about collecting and storing data, creating high-resolution imagery and virtual 3D models, creating digital renderings of figures and panels, deducing super-positioning and sequences of figure placement, collecting objective color data, assessing chemical composition of paint, and collecting geospatial data. Preregistration is Required.

OBSI: Obsidian Hydration Dating Workshop
Instructor: Alexander (Sandy) Rogers

March 4, 2021, 8:00 a.m. – 12:00 p.m. Cost: $40.00

As with all chronometric techniques, obsidian hydration dating cannot be treated as a black box. The goal of this workshop is to provide insight into the theory and methods of obsidian hydration dating (OHD). It should enable the archaeologist to perform OHD analyses and the manager to ask the right questions. The workshop will cover the basic principles of obsidian hydration and the models employed in dating; how to develop an appropriate effective hydration temperature (EHT); various methods of computing a hydration rate; guidelines for data analysis; and numerous cautions. An Excel spreadsheet with numerical models for conducting an OHD analysis will be provided, and we will do some hands-on exercises. Mathematics will be kept to a minimum but cannot be avoided entirely. Some familiarity with Microsoft Excel is desirable, so please bring your laptop with Excel. Preregistration is Required.
