Mammoth hot springs at Yellowstone National Park
Bruce Fouke and Nigel Goldenfelds group at the
University of Illinois at Urbana-Champaign are
studying whether or not microbial metabolic
activity plays a significant role in the
deposition of these travertine terraces by the
degassing of CO2. Can we use observation of
certain geological structures to infer the
existence of microbial life? On Earth? On Mars?
