I joined EarthScope investigators Christine Siddoway and Megan Anderson (Colorado College) and Eric Erslev (University of Wyoming) on a 4-day structural geology tour of the Bighorn Mountains in northern Wyoming. A group to be led by Megan will install seismic stations throughout the range this summer as part of the Foreland Basement Arch Seismic Experiment. Christine and Eric have students starting fieldwork in the Bighorns for structural geology theses. For all who are involved in the work this summer, the field trip provided an introduction to the regional geology of the Bighorns basement arch. Continue reading Day 1 (6/22/09): Across the Bighorns
