Sat Sept 13, 2013: Obsidian Quarry tour with BLM Archaeologist Greg Haverstock

Bodie Obsidian

We will join BLM Archaeologist Greg Haverstock and visit one of the most significant sources of obsidian in prehistoric California. Participants will learn about obsidian analyses and how these data are used by archaeologists to reveal prehistoric behavioral patterns. The discussion will include details about the temporal use of the Bodies Hills obsidian source, the spatial distribution of obsidian through trade and travel, geo-chemical variation in obsidian, and obsidian hydration dating. Participants will also become familiar with obsidian tool manufacture, see prehistoric examples of this process, and learn about changes in obsidian use during the Holocene.

This outing is rated as easy, with minimal elevation gain and loss during this outing. Participants are encouraged to bring binoculars, a camera, sun screen, hat, a sack lunch, 2-3 liters of water. Long pants and comfortable hiking shoes are also recommended.

Important info: 2 miles or less walking - No 4WD required, high clearance helpful.
