Joseph S. Diller published the first
geology of Crater Lake in 1902, the same year the area became a
national park. In his work, Diller briefly describes a great trunk he had found in the lake six years earlier, in a report dated 1896. Preliminary
carbon dating of the trunk has suggested that the tree itself is at least 450 years old. Diller established that the trunk could travel by tying baling wire around it and pulling it a short distance. Five years later, Diller observed the Old Man to be from the location he had previously noted. , the entire submerged section of the tree's trunk can be seen below the waterline. ==See also==
