![]() US Geological Survey, USGS The underwater landscape of Crater Lake was mapped in 2000. this collection imagery and data was a cooperative effort between the U.S. Geological Survey's Pacific Seafloor Mapping Project, the National Park Service, and the Center for Coastal and Ocean Mapping at the University of New Hampshire. A state-of-the-art multibeam sonar system collected high-resolution bathymetry, and calibrated co-registered acoustic backscatter to support both biological and geological research in the area (aquatic biology, geochemistry, volcanic processes, etc). This survey collected over 16 million soundings and the resulting data portrays the bottom of Crater Lake at a spatial resolution of 2 meters.

"Fly-by of shaded-relief bathymetry and surrounding mountains of Crater Lake Oregon. The colored region is the lake floor whereas the gray region shows the surrounding mountains. The lake is approximately 9-km wide east to west. The flight approaches from the south, flies around the lake floor in a clockwise direction, passes over Wizard Island, Merriam Cone, the deep East Basin, the Central Platform, and Rhyodacite Dome."
