                                               Venue
                                                  The Department of Geology at Utah State University will serve as host for this joint meeting
                                               (cosponsored by Central Washington University) at the Riverwoods Conference Center in
                                               Logan, Utah, USA. Logan is situated at a nexus of western geology, with the Rocky Mountains
                                               to the east, the Basin and Range to the west, and the Snake River Plain to the north. Geologic
                                               formations near Logan range in age from paleo-Proterozoic to Quaternary and in character
                                               from crystalline to karst. Theme sessions and field trips reflect this range of exposure and offer
                                               something for all interests and disciplines, including one-day trips to local outcrops and multi-
                                               day trips to Idaho, Nevada, Oregon, Wyoming, and Utah.
                                                  The Riverwoods Conference Center, 615 S. Riverwoods Parkway, Logan, Utah 84321,
                                               USA, is located on the banks of the Logan River where it flows through downtown Logan,
                                               about two miles from the university campus.

theme Sessions
1.   From Contraction to Extension: The Mesozoic to Cenozoic Tectonic Evolution
     of the Northern Great Basin. Joseph P. Colgan, USGS, jcolgan@usgs.gov; Chris Henry,
     Univ. of Nevada–Reno, chenry@unr.edu; Victoria E. Langenheim, zulanger@usgs.gov; Allen
     J. McGrew, allen.mcgrew@notes.udayton.edu; David M. Miller, dmiller@usgs.gov.
        This session focuses on the integrated Mesozoic-Cenozoic tectonic history of the Great
     Basin, especially the interplay of continental contraction, extension, and magmatism.
     The region is noted for its hinterland core complexes, magmatic history, thrust belts,
     extensional tectonics, and basins. New geologic mapping, structural analyses, geo- and
     thermochronology, and thermobarometry and petrology have introduced new ideas
     and controversies. Presentations on these new results, perspectives on advances in
     understanding, and topics related to the timing and causes of the change from contraction
     to extension are particularly encouraged.
2.   Interactions of Climate, Tectonics, and Sedimentation in Cenozoic Basins of
     the Basin and Range. Thomas Hickson, Univ. of St. Thomas, tahickson@stthomas.edu;
     Melissa Lamb, Univ. of St. Thomas, malamb@stthomas.edu; Paul Umhoefer, Northern
     Arizona Univ., paul.umhoefer@nau.edu.
        Sedimentary basins provide perhaps the single best opportunity to develop an
     understanding of how extensional landscapes evolved over long timescales under
     conditions of changing climate and complex tectonic deformation patterns, yet—when
     compared to compressional settings—little work has been completed that addresses
     these interactions. New lithostratigraphic, chemostratigraphic, and stable isotopic data,
                                                                                                     Utah State University with the Bear River
