Pardee Keynote Symposia are named in honor of GSA Fellow and benefactor Joseph Thomas Pardee (1871–1960) via a bequest from Mary Pardee Kelly. Pardee is perhaps best known for his work on Glacial Lake Missoula. These symposia consist of invited presentations covering a broad range of topics.
P1. The Changing Face of Geoscience in the 21st Century: Increasing Diversity and Inclusion to Solve Complex Problems
GSA Geology and Society Division; GSA Committee on Diversity in the Geosciences; Earth Science Women’s Network; International Association for Geoscience Diversity; Geoscience Alliance; Association for Women Geoscientists
Sunday, 22 October 2017, 2–5:30 p.m., Ballroom 6A
Barbara P. Nash; Carol B. deWet
The changing face of the geosciences is a response to global challenges, climate, resources, the environment, energy and sustainability. The lack of diversity in the geosciences limits perspectives, experiences and innovative approaches to solving critical problems that the geosciences are well poised to address. The symposium will (1) examine how the changing face of the geosciences necessitates that we develop an diverse workforce; (2) share experiences of geoscientists from diverse backgrounds who have contributed fresh perspectives and experiences to help produce scientifically effective and socially responsible solutions; and (3) examine strategies to create a geoscience workforce that leverages diversity.

P2. Landscapes in the Anthropocene
GSA Quaternary Geology and Geomorphology Division; GSA Geology and Society Division; GSA Hydrogeology Division; GSA Geology and Public Policy Committee; Geology (journal)
Monday, 23 October 2017, 8 a.m.–5:30 p.m., Ballroom 6A
José Antonio Constantine; J. Wesley Lauer; Rónadh Cox
Intensifying pressures driven by changes in climate and land use may be pushing many of Earth’s landscapes toward tipping points. In most cases, our ability to predict this transition is being outpaced by the rates of landscape change, and we are consequently not meeting the needs of communities whose land is threatened by environmental upheaval. This symposium will bring together a trans-disciplinary group of innovative thinkers who are grappling with landscape change. Either by developing predictive models or by translating science into policy, our speakers are all working at the cutting-edge of increasingly pervasive environmental challenges typical of the Anthropocene.

P3. IODP-ICDP Expedition 364 to the Chicxulub Impact Crater
GSA Planetary Geology Division; GSA Geophysics Division; International Continental Scientific Drilling Program (ICDP); European Consortium for Ocean Research Drilling (IODP-ECORD); Lunar and Planetary Institute (LPI)
Tuesday, 24 October 2017, 8 a.m.–noon, Ballroom 6A
David A. Kring; Philippe Claeys
Sixty-five million years ago, the evolution of Earth was dramatically altered by the Chicxulub impact event. This icon of the impact-mass extinction hypothesis was targeted by IODP-ICDP Expedition 364 to test models of peak-ring formation, impact-generated hydrothermal systems, habitability within those systems, and the recovery of life in the vicinity of the crater. This Pardee Keynote Symposium will reveal first-year studies of a borehole that pierced the PETM, the Paleogene sediments that cover the crater, impact-melt bearing units on the floor of the crater, and the granitic core of a peak-ring that was uplifted ~10 km in a geologic instant.

P4. Speed Dating!: Advice on Sampling and Applications Through the Lens of the Geochronologist (Posters)
GSA Quaternary Geology and Geomorphology Division; GSA Archaeological Geology Division; GSA Karst Division; GSA Limnogeology Division; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division; GSA Sedimentary Geology Division; GSA Structural Geology and Tectonics Division
Tuesday, 24 October 2017, 9 a.m.–6:30 p.m., Halls 4EF
Tammy Rittenour; Michelle Summa Nelson; Shannon A. Mahan
Age control is an essential aspect of most geologic research. However; the first step toward obtaining accurate age estimates relies on the individual researcher to correctly select and collect suitable material for dating. For best results, researchers need to assess site and sample conditions through the lens of the dating specialist. This unique booth-style Pardee session will facilitate discussion and one-on-one interactions between geochronology specialists and users of the techniques, such as students, researchers; and other professionals in the field.

P5. Origin, Accretion, and Translation of Mesozoic-Cenozoic Terranes along the Pacific Margin of North America
GSA Structural Geology and Tectonics Division
Tuesday, 24 October 2017, 1:30– 5:30 p.m.,Ballroom 6A
David T. Katopody; Mark T. Brandon; Bernard Housen
The Mesozoic to Cenozoic evolution of the western margin of the North American Cordillera has been the center of a long-standing controversy about the mobility of crustal fragments along continental margins. This symposium will outline the major lines of evidence for accretion and coastwise transport during the late Mesozoic and into the Cenozoic and will serve as a forum to identify remaining problems and opportunities in Cordilleran tectonics.
P6. Earth Anatomy Revealed: Geologic Mapping for Our Future
GSA Geology and Society Division; GSA Geology and Public Policy Committee; GSA Geoinformatics Division; Association of American State Geologists; American Geosciences Institute; American Institute of Professional Geologists; American Geophysical Union; U.S. Geological Survey
Wednesday, 25 October 2017, 8 a.m.–noon, Ballroom 6A
Darcy K. McPhee; Cassaundra A. Rose; L. Harvey Thorleifson; Danielle N. Woodring
How does geologic mapping underpin our research, and help solve pressing societal issues? How are expectations changing on what a map can do? What new innovative technologies are at the forefront of geologic mapping? During the morning of October 25, 2017, please join the discussion at GSA in Seattle at the Pardee Symposium, "Earth Anatomy Revealed: Geologic Mapping for Our Future." The discussion will feature leaders from across the geoscience community including the U.S. Geological Survey Director, senior leaders from national organizations and state geological surveys, experts from user communities, and innovation leaders. See you there!
