Scientists get better look at lake bottom By Paul Fattig For more than 20 years, Charlie Bacon conducted his research of Crater Lake with blurred vision. But it has all became crystal clear for the volcanologist at the U.S. Geological Survey office in Menlo Park, Calif., thanks to recent mapping of the caldera with the latest deep-sea technology. Until the mapping by a team from the USGS, the National Park Service and the University of New Hampshire late last month, scientists studying the deepest lake in the nation relied on maps made by less sophisticated sonar in 1959, ore samples taken from the lake bottom and research by submersibles in 1988-89. We haven t found any shockers yet, but there has already been a lot of confirmation of things we ve interpreted earlier. The brightly colored, computer-generated images look almost psychedelic.
