History through the Volcanic Glass Window
Flows of obsidian, a natural glass produced by many volcanoes in Oregon, contain a unique chemical signature that enables archaeologists to trace artifacts back to the volcano of origin. Obsidian is also an unstable mineral that produces a “hydration clock” that tells the age of each artifact and flake.
Obsidian artifacts yield a treasure-trove of information about prehistoric ways of life and the development of sociopolitical areas in central Oregon across fifteen thousand years of prehistory. Archaeologist Dennis Jenkins presents a fascinating look at the trail of information left by this beautiful volcanic glass.
Lake County Libraries are pleased to host this Oregon Chautauqua from the Oregon Council for the Humanities. OCH is an independent, nonprofit
