Crater Lake

Crater Lake in Oregon was first discovered by white explorers in 1853. A couple of years later, William Gladstone Steele saw the lake and made it his mission to establish the lake (6 miles in diameter) and surrounding area (286 square miles) as a national park, which finally took place in 1902. The lake is within a volcanic caldera and it may be a remnant of Mount Mazama, a volcano that rose to probably 12,000 feet until an eruption about 7,000 years ago destroyed the upper portion - or it may be of meteoric origin. Its maximum depth is 1943 feet, making it the deepest lake in the United States and the seventh deepest in the world. Its waters are extremely clear and it is often possible to see to a depth of more than 100 feet.
