Crater Lake reaches a depth of 1,943 feet, making it the deepest lake in the United States and the ninth deepest in the world.
Crater Lake was formed over 7,700 years ago when Mount Mazama, a volcano, collapsed after a major eruption.
The lake's intense blue color is due to its depth and clarity, allowing sunlight to penetrate deep and scatter blue light.
The lake is filled entirely by rain and snow, which contributes to its purity and clarity.
A 30-foot-long tree trunk has been floating vertically in Crater Lake for over a century, known as the 'Old Man of the Lake.'
Crater Lake National Park, established in 1902, is the fifth oldest national park in the United States.
Wizard Island is a volcanic cinder cone that rises 763 feet above the lake's surface, formed after the caldera collapse.
The lake is home to two species of fish: rainbow trout and kokanee salmon, introduced in the late 19th century.
