Tuesday, July 29: Seismic mapping at Gypsum Springs

Sean, a high school teacher from Sacred Heart School in Stittsville, Canada, calibrates a seismometer yesterday, as the CSA crew collects initial seismic data in a quest to learn what geology underlies Gypsum Springs' outlets.  We hope this will help us understand why different spring outlets have widely differing water temperatures even though there are only a few feet away from each other.
