| AN IMPORTANT 2012 SUMMER LAB SCHEDULE NOTICE: The XRF lab will be closed during the summer months (June 1-September 1) and you'll need to get any projects into the lab by June 1st. We've been a little wishy-washy about this schedule in the past but must hold to it this summer because of several significant obligations that we must meet. PLEASE NOTE: The hydration laboratory will remain open as usual during this period. For more details about our annual summer schedule, click HERE.

| UPDATED DOWNLOADS: We've reorganized the lab downloads and have relocated most of the obsidian-related articles, reports, theses, and dissertations to the new IAOS PDF Library. Our standard lab forms and other docs can still be found HERE.

| 
|
| NEW EXPANDED ONLINE OBSIDIAN SOURCE RESOURCES: We're gradually expanding the source descriptive and literature reference information at the U.S. Obsidian Source Catalog. This project is still rough around the edges but you can see where we're going with it by looking at the SOURCE REFERENCES menu located to the left. Click HERE for more information.

| ADDITIONAL OBSIDIAN AND FGV SOURCE MAPS ARE NOW AVAILABLE: We're just finished (again) producing and updating several obsidian and FGV source maps for the western United States and are continuing to add to our map library collection on a regular basis. To see our latest additions, click HERE.

| FEATURED RESEARCH: ODELL LAKE SITE: In 1937, Luther Cressman and his associates from the University of Oregon excavated a pre-Mazama site at Odell Lake in the Oregon High Cascades. In this report, we focus the X-rays on the artifacts that were recovered at that time.

| 
|
| PANORAMAS: From time to time, we add a new 360 degree interactive panorama to our collection. To see our latest 2011 additions, click HERE.
