Detailed Description

Dr. Kenneth Pierce studied the geology and geomorphology of the greater Yellowstone area for nearly his entire career with the U.S. Geological Survey. From 1965 to present, Dr. Pierce has mapped glacial deposits, pioneered Quaternary dating techniques, conducted research on the Yellowstone Hot Spot, studied the geothermal areas, explored the geology of archaeological sites around Yellowstone Lake, and led field trips into the Park. In this video, Dr. Pierce discusses his work at Yellowstone Lake and how he was able to detect subtle inflation and deflation (or “heavy breathing”) attributed to the subsurface movement of geothermal fluids. Dr. Pierce also talks about his work advising Montana State University students.
