Exploration and Discovery in Yellowstone Lake: Results from High-resolution Sonar Imaging, Seismic Reflection Profiling, and Submersible Studies

Morgan Lisa, U.S. Geological Survey

This journal article presents discoveries from multi-beam sonar mapping and seismic reflection surveys of Yellowstone Lake. It provides new insight into the extent of post-collapse volcanism and active hydrothermal processes occurring in a large lake environment above a large magma chamber. The article contains extensive text, photos, maps, and diagrams to support findings.
