In Search of Geysers

WHOI students and scientists investigate Spray Geyser during a field trip to Yellowstone National Park in Wyoming. The trip culminated the 2015 Geodynamics Program, a semester-long series of seminars by scientists that this year focused on hydrothermal systems. The group followed the track of the Snake River Plain-Yellowstone hotspot. As the continent moved over the hotspot, it formed the Snake River Plain in a succession of volcanic eruptions. The hotspot now lies under Yellowstone National Park, where geysers and hydrothermal features are still active.(Photo by Rob Sohn, Woods Hole Oceanographic Institution)
