The Yellowstone Field Trip was made possible by the Storke Memorial Fund, designated to support educational activities at Lamont-Doherty Earth Observatory, Columbia University. The field trip was sponsored by the Department, organized by graduate students, and led by Professor Mark Anders.  Eighteen current students and one former student participated in the 10-day trip. A student-produced field guide for the trip will is available below.

Seminar

A student-led seminar series laid the foundation for this field trip. The students met 8 Wednesdays in May and June for a total of 16 hours. Each participant presented a topic of interest to the rest of the group and led the discussion.  A complete list of references by topic is available in the field guide.

Field Guide

In summer 2011, over nine days, a group of Columbia University graduate students visited four states and covered well over 1000 miles of Rocky Mountain geology. The group started in Denver, Colorado and traversed parts of Wyoming, Idaho, and Montana. Of the many geological attractions of Wyoming, Yellowstone National Park located over Yellowstone Hotspot is possibly the crown jewel. Yellowstone is the largest volcanic system in North America and the associated geothermal activity produces the largest active geysers in the world, as well as thousands of other fascinating geothermal features. In addition to Yellowstone National Park, Wyoming also offers opportunities to observe characteristic geologic features of the Western United States: manifestation of Sevier and Laramide orogenies, Basin and Range extensional features, regional stratigraphic units, dinosaur tracks, catastrophic landslides, effects of Yellowstone hotspot volcanism, and much more. This field guide describes a number of convenient locations to observe and explore these features, and provides background information about major geologic processes that shaped this region over time.
