Obsidian in the Ancient American Southwest
Archaeology 101 Series with Sean Dolan

Each flow of this volcanic glass has a unique geothermal fingerprint, allowing archaeologists to trace social interaction, trade, and mobility in ancient times. Lecture delivered by Sean Dolan, a LANL archaeologis and UNM graduate student.
