A floating tree log known as the“Old Man of the Lake”has been bobbing in the blue water of Oregon's Crater Lake for at least 120 years, baffling(使……困惑) scientists with many mysteries.rnThe first account of the“Old Man of the Lake”dates back to 1896, when geologist and explorer Joseph Diller described a splintered(裂开的) and bleached(褪色的) white log floating vertically in Crater Lake, the deepest lake in the United States, and the ninth deepest in the world. Five years later, Diller observed that the unusual log had moved 400 meters from the location it had originally been spotted at.
