UW-Eau Claire Students, Faculty and Alumni to Present at GSA Annual Meeting Oct. 16-19

RELEASED: Oct. 3, 2005

EAU CLAIRE — The University of Wisconsin-Eau Claire will be well represented at the 117th annual meeting of the Geological Society of America, Oct. 16-19, at the Salt Palace Convention Center in Salt Lake City, Utah. Eight students, four UW-Eau Claire graduates and six faculty members have been chosen to present at this year's GSA meeting.

Gillian Krezoski, a senior from Glendale, double-majoring in history and geology, will present "Depositional Environments of the Mississippian (Chesterian) Loyalhanna Member of the Mauch Chunk Formation at the Keystone Quarry in Southwestern Pennsylvania," which details research done in collaboration with Dr. Karen Havholm, professor of geology at UW-Eau Claire.

Senior comprehensive geology major Joseph Nawikas, Sheboygan, will present "Structural and Magmatic Evolution of the Helena Salient: New Geologic Mapping in the Devils Fence Anticlinorium," along with student co-authors Adam Kjos, New London, John Stoltz, Spring Green, Christopher Kohel, Westfield, and Catherine MacLaurin, Belgium. This research was conducted with Dr. J. Brian Mahoney, professor of geology, and Dr. Phillip Ihinger, associate professor of geology at UW-Eau Claire, with support from the State of Montana and the U.S. Geological Survey.

Mahoney and Ihinger also will make presentations.

Mahoney will present "Variations in Late Cretaceous Batholith Exhumation Patterns along the Western North American Margin," along with co-authors David Kimbrough, San Diego State University; Marty Grove, University of California- Los Angeles; and Carl Jacobson, Iowa State University.

Ihinger will present "The Yellowstone Plumehead, Mid-Sized Igneous Provinces, and Cenozoic Structural Deformation of the North American Cordillera: A Single, Prolonged Tectonic Event," which details research done in collaboration with two former UW-Eau Claire graduates, Breck Johnson (2004 UW-Eau Claire graduate now at University of North Carolina-Chapel Hill) and James Watkins (2005 UW-Eau Claire graduate now at University of California-Berkeley).

Suzanne Reed, Elkhorn, graduated in May of 2005 with a degree in general geology but is continuing her research on the Hazelton strata in British Columbia for the annual GSA meeting. Reed, along with student co-author Adam Kjos, will present research from the project "Record for Mesozoic Orogeny and Back-Arc Basin Formation and Magmatism in Western Stikinia; Evidence from Strata at John Peaks, Eastern Iskut River Area, Northwestern B.C." This research was done in collaboration with Lori Snyder, senior lecturer; J. Brian Mahoney; and Robert G. Anderson, Geological Survey of Canada.

Lisa Johnson, Spencer, a 2003 UW-Eau Claire elementary education graduate, will present at GSA, for a third time, her research into techniques and teaching materials for visually impaired geology students. Johnson and geology professor Karen Havholm worked together to develop several methods that enable visually impaired students to be more actively involved in field studies, laboratory activities, lectures and homework. Johnson, who is visually impaired, was inspired to do the research study after enduring a semester-long geoscience course that relied heavily on sight for observation, gathering data and reporting the earth's history. In 2003 USA Today recognized her efforts and named her to their annual All-USA College Academic First Team. Johnson last presented this topic in 2004 at GSA's annual meeting in Denver, Colo. According to Johnson, everyone is entitled to a good education, and as long as the research tools and techniques she developed enable one person to succeed, she will be pleased.

Dr. Colin Shaw, assistant professor of geology at UW-Eau Claire, will present "Age, Setting, and Reactivation of the Grizzly Creek Shear Zone: Tectonic Implications of a Newly Recognized Brittle/Plastic Thrust in Central Colorado." Coauthors of the presentation include UW-Eau Claire students Abbey Graves, Green Bay, and Shawn Lyman, La Crescent, Minn., as well as Dr. Joseph Allen and four students from Concord University, West Virginia.

Dr. Robert Hooper, professor of geology at UW-Eau Claire, will present "A Coordinated Tem and ICPMS Study of Metal Sequestration in Colloids and Nanoparticles in the Lower Coeur D'Alene River Valley Northern Idaho." This research is a collaborative effort with co-author J. Brian Mahoney, and undergraduate researcher Brandon Barber, Sauk City, in the department of geology.
