Keck Geology Consortium Member schools Amherst College Beloit College Carleton College Colgate University Franklin & Marshall College Macalester College Mt Holyoke Oberlin College Pomona College Smith College The College of Wooster The Colorado College Trinity University Union College Washington and Lee University Wesleyan University Whitman College Williams College The Keck Geology Consortium is focused on enriching undergraduate education through development of high-quality research experience. As an independent organization, housed at Franklin & Marshall College, the Consortium establishes its program priorities based on the educational philosophies of the member colleges: dedication to excellence in undergraduate education, offering students comprehensive and rigorous educational opportunities that promote intellectual growth, integrity, responsibility, and a sense of both individuality and membership in community. The Consortium has been a fundamental component of the undergraduate-research landscape for 20 years, supporting more than 980 students from over 80 schools across the nation. "Keck" has a tangible meaning in the geoscience community: talented students gaining field experience supported by dedicated, master teachers. LEARN MORE ABOUT THE CONSORTIUM... Special Announcement: ****Session in honor of Al Curran at 2008 GSA in Houston**** Students! Interested in participating in a Keck Research Project? Projects for 2008/2009. 2009/2010 projects will be announced in December, 2008.
Keck Colorado/Boulder Project CZO-2008 • EveyGannaway—Suwanee-University of the South • Ken Nelson—Macalester College • Miguel Rodriguez—Colgate University + EirikBuraas—Williams College • David Dethier(Williams College) and Matthias Leopold (Technical University of Munich)….and many others!
Keck/CZO Colorado Project 2008 Eirik Evey Ken Miguel Soils Fractures Apatite Water
Getting water into the ground, upper Gordon Gulch, Colorado Eirik M. Burass and David P. Dethier Department of Geosciences, Williams College
Introduction How does water get to the channel in Gordon Gulch and how are the pathways controlled by infiltration rates? What controls infiltration rates? Field methods • Map bedrock outcrops • Map roads and motorbike/ATV • /mountain bike trails • 3.Measure infiltration rates at • selected sites using a double-ring • infiltrometer
Roads, trails and cuts, Gordon Gulch Fuelwood reduction
Hauling water and infiltration Low rates can be good
Infiltration tests, meadow site And high rates demand many hands!
Infiltration results, Gordon Gulch “Excessive”
15 mm/hr? Gordon Gulch 9 August 2008
Eirik’s future work? • Outcrop data into polygons • Analyze the infiltration data • Texture/OM analyses on • selected samples • Analyze/model (?) the effects • of low-permeability surfaces
