Mount Shasta is one of the largest of the High Cascade stratovolcanoes and has an eruptive history that spans the past 700,000 years. Two of the peak’s five major cones have grown since Pleistocene glaciers retreated from the mountain about 11,400 years ago, however, and the potential for future eruptive and debris flow events remains high. Although basement rocks are poorly exposed on and around the mountain, scattered outcrops and the chemistry of some flank lavas suggest it stands atop serpentinite and marine sedimentary and volcanic rocks of the Eastern Klamath terrane. This course will introduce the tectonic setting, eruptive history, and potential hazards of Mount Shasta as well as briefly exploring the ancient basement rocks that may underlie it and influence the chemistry of some of its lavas.

Inexpensive dorm lodging is available at College of the Siskiyous in Weed. Call SFI at 541-597-8530 for details.
