Six members of Colorado College’s geology department will present their research at the2011 annual meeting of the Geological Society of America, to be held Oct. 9-12 in Minneapolis. Those presenting are Ashley Contreras ’12, Eleanor Emery ‘12, and Benjamin Mackall ‘11, as well as Associate Geology Professor Henry Fricke, Geology Professor Christine Siddoway, and Geology Technical Director Stephen Weaver.
Contreras, who worked with Siddoway, will present a paper titled “New Insights on the Timing and Extent of Cretaceous Exhumation in the West Antarctic Rift System, from U-PB and (U-TH)/HE Zircon Analysis. Emery, who also collaborated with Siddoway, will present a paper titled “Use of Stereoscopic Satellite Imagery for 3D Mapping of Bedrock Structure in West Antarctica: Example from the Ford Ranges and Neogene Volcanoes of Marie Byrd Land.” Mackall, who collaborated with Geology Professor Eric Leonard, will present a paper titled “Estimates of Last Glacial Maximum Climate of the Snowy Range, Southern Wyoming, using Numerically Modeled Paleoglacier Reconstructions.”
Fricke’s research is titled “Stable and Clumped Isotope Study of Authigenic Carbonates from the Kootznahoo Formation, Alaska, and Implications for Study of Paleogene Climate and Hydrology.” Siddoway will present research titled “Potential Sources of Crustal Anisotropy in the Wyoming Province: Insights from Basement Structures of the Bighorn Mountains, Wyoming.” Weaver, who shoots the cover photos for Colorado College’s annual State of the Rockies Report and subsequent poster, will present “Beyond the Snapshot: Making the Excellent Geo-Photograph in the Field.”
Researchers have developed a new way of determining the body temperatures of dinosaurs, providing new insights into whether dinosaurs were cold-or warm-blooded.
A paper co-written by Associate Geology Professor Henry Fricke discusses the techniques used to determine the body temperature of animals that have been extinct for 150 million years.
By analyzing the teeth of sauropods — long-tailed, long-necked dinosaurs that were the biggest land animals ever to have lived — the scientists found that these dinosaurs were nearly as warm as most modern mammals.

The research was funded by the National Science Foundation’s division of earth sciences
Tia Wood ’10, a current paraprofessional in the geology department, competed with graduate and undergraduate students at the American Geophysical Union conference, held in December 2009 in San Francisco. Wood was awarded an “Outstanding Student Paper Awards” for her presentation “Anisotropy and mantle flow in the eastern Sierras Pampeanas from shear wave splitting” in the Study of the Earth’s Deep Interior category.
Colorado College has received more than $2.3 million from the James W. Austin Charitable Remainder Unitrust, which will go toward a scholarship fund providing unrestricted financial aid. The donation is the single largest life income gift in the history of Colorado College.
The funds will establish the James W. and Esther Austin Scholarship Fund, in memory of Austin and his wife. James W. Austin graduated in 1929 from Colorado College with a degree in geology.
The gift to fund the Unitrust was originally made in 1993. Austin received monthly payments from his Unitrust until his death in 1997; payments then went to beneficiaries, the last of whom died in August 2009. The remaining principal and interest of the Unitrust will now go to Colorado College to establish the scholarship fund.
Austin was an alumni trustee at Colorado College from 1958-60. He was awarded CC’s Louis Benezet Award in 1991 for outstanding professional achievements.
Colorado College Education Professor Mike Taber has been elected president of the National Association of Geoscience Teachers. Taber, who is director of the secondary teaching program and director of the environmental program at CC, will serve as president for a year. He was formally inducted at the Geological Society of America meeting held in Portland, Ore., in mid-October. The National Association of Geoscience Teachers works to raise the quality of and emphasis on teaching the geosciences at all levels.
