Crater Lake stuns visitors with its natural beauty and the story behind its rare formation. But much of that gorgeousness begins to fade when more tales about the caldera come to light. Namely, the United States’ deepest lake has set the scene for some terrifying, mysterious deaths. Just ask the guy who hiked the grounds, rested on a tree trunk, and then saw a person’s skull staring back at him.
Nearly 8,000 years ago, a volcano called Mount Mazuma crumbled to the ground. This left a gaping, half-mile-deep caldera in Oregon. Over time, rainwater and mountain run-off filled the void to create a body of water that’s 1,949 feet deep at some points. It’s the deepest lake in the U.S., and the ninth deepest on Earth, when measured at its deepest point.
