OREGON’S FAMOUS CRATER LAKE NOT 1,000 YEARS OLD

Blue Crater Lake, in the national park of that name, at last has divulged the secret of its age. Not all at once, however. A few facts it revealed to the geologist, a few more to the student of tree rings, others to the engineer. Putting two and two together, these various specialists have come to the conclusion that Crater Lake is young, not yet 1,000 years old.
