In 2010, a group of seismologists deployed several hundred sensors across Wyoming and Montana as part of EarthScope's Bighorn Project and the Bighorn Arch Seismic Experiment (BASE). EarthScope/EPIC supplied instruments and expertise as part of this large effort, which included scientists from CIRES at University of Colorado Boulder(1), the Department of Geology at Colorado College(2), the Department of Geology and Geophysics at the University of Wyoming(3), and the Department of Geology and Geophysics at Texas A&M University(4). The Principal Investigators included Anne F. Sheehan(1), Megan L. Anderson(2), Eric A. Erslev(3), Kate C. Miller(4), and Christine S. Siddoway(2). William L. Yeck(1), the lead graduate student from UC Boulder, provided analysis and support included in this article. Additionally, numerous students contributed to the effort. The team's recent publication, "Structure of the Bighorn Mountain region, Wyoming, from teleseismic receiver function analysis: Implications for the kinematics of Laramide shortening," is available from AGU Publications (Full, PDF).
