The bathymetry survey of Crater Lake by scientists from the USGS, University of New Hampshire's Center for Coastal and Ocean Mapping, and the National Park Service, began on July 28, 2000. This site houses the first images gained from the high-resolution multi-beam technology survey. Various digital data such as digital raster graphics and digital line graphs may be viewed as .jpeg and .gif images or downloaded as .zip files. Besides the bathymetric data, the site features information on the geology, ecology, and history of Crater Lake, and beautiful .gif images of the lake and surrounding areas.
