UNITED STATES AND CANADA OBSIDIAN SOURCE CATALOG
Welcome to the U. S. and Canada Obsidian Source Catalog. This catalog is maintained by Northwest Research Obsidian Studies Laboratory so that we may provide support and information for our clients and for the archaeology community in general. Please keep in mind that the U. S. obsidian source catalog project provides only a snapshot of what currently remains a moving research target - geoarchaeological and geochemical investigations of obsidian sources and artifacts are an area of active research and new sources are still being located, relocated, and geochemically identified on a regular basis.
Looking for the IAOS World Obsidian Source Catalog? Click HERE to head to the original World Obsidian Source Catalog hosted by the International Association for Obsidian Studies. At that location, you can find additional information about the many other obsidian sources located throughout the world.
Protection of Prehistoric Resources: Many of the obsidian sources listed here are associated with the prehistoric procurement of natural glass. Please do not collect artifacts at these sources. This may not only be illegal but irrevocably erases and destroys the archaeological history of these significant areas. Strict limits on the amount of geologic material removed may be maintained and collection permits may be required for obsidian found on public lands (inquire locally). Please limit flintknapping activities to well-recognized areas so that the archaeological record remains as undisturbed as possible.
Additional Obsidian Source Information Availability: Bibliographic information and details about individual obsidian sources are gradually becoming available in the form of Adobe Acrobat documents (PDF's) that are linked to the state source lists. Initial source information is currently limited but is expanding over time.
Obsidian Source Maps: Obsidian source maps for many of the western states in the U.S. are now available or soon will be finished. Click HERE to see the collection.
