Four-day trip over Memorial Day weekend (involving light hiking and camping) to study silicic and mafic volcanism in the eastern Sierra Nevada: basaltic lavas and cinder cones erupted along normal faults bounding Owens Valley, Long Valley caldera, postcaldera rhyolite lavas, hydrothermal alteration and hot springs, Holocene rhyolite lavas of the Inyo and Mono craters, subaqueous basaltic and silicic eruptions of Mono Basin, floating pumice blocks. If snow-level permits, granites of Yosemite and/or silicic volcanism associated with the Bodie gold district. Recommended: 1 or equivalent. Limited enrollment; preference to frosh, sophs, and undergraduates and graduates majoring in SE3.

For juniors, seniors, and beginning graduate students. Eruptive processes that create volcanic deposits and landforms; shield, stratocone, and composite volcanoes, lava dome fields; calderas. Control of magma viscosity and water content on eruptive style. Fluid dynamic controls on the characteristics of lavas and pyroclastic flows. Submarine and subglacial eruptions and interaction of magma with groundwater. Rhyolitic supereruptions and flood basalts: effects on climate and atmospheric chemistry, relation to extinction events. Volcanic hazards and mitigating risk. Geophysical monitoring of active volcanoes. Volcanic-hosted geothermal systems and mineral resources. Those taking the class for 4 units will complete a 3-hour weekly lab that emphasizes recognizing types of lavas and products of explosive eruptions in hand specimen and thin section. Prerequisite: 1, for those taking the course for 3 units; 103 and 104 or equivalent for those taking the course for 4 units.

Month long courses that provide students with the opportunity to collect data in the field as part of a team-based investigation of research questions or topics under the expert guidance of knowledgeable faculty and graduate students. Topics and locations vary. May be taken multiple times for credit. Prerequisites: GS 1, GS 102, GS 105.

Four- to seven-day field trips to locations of geologic and environmental interest. Includes trips offered during Thanksgiving and Spring breaks. May be repeated for credit.

Field-, lab-, or literature-based. Faculty supervision. Written reports. May be repeated for credit.
