Volcanology in the High Lava Plains

406 (undergraduate) or 606 (graduate) – Field Studies: Volcanology and Active Faulting (3 credits)

Students will learn to identify, map, and interpret volcanic and active fault features in the High Lava Plains of Central Oregon. In this project, students will make a detailed geologic map of the flows and cinder cones of the Four Craters field from stereo air photos and determine the sequence and volume of different eruptions.  There will also be two field trips to learn more about the volcanism and active faulting of the Oregon High Lava Plains and Basin and Range Provinces.

The group will be camping in tents for this segment. Students should be prepared to live in a tent for 10 days. Large tents with tables will be provided for group cooking, equipment storage, and working on maps at night. All equipment and utensils for meals will be provided. Students should bring their own tent, sleeping bag and pad, towel, and plenty of warm clothing. See the equipmentlist for details.

Students are advised that work will be physically strenuous and will involve hiking on steep and irregular terrain, generally during hot weather. Graduate students will synthesize the results of field work and submit summary maps and/or a report within two weeks after we return from the field.

More information for this course will be posted soon.
