Crater Lake

Crater Lake was formed inside a volcanic caldera following the cataclysmic eruption of Mount Mazama, which occurred approximately 7,700 years ago. The summit of the volcano collapsed, creating a massive basin that eventually filled with water from rain and snowmelt. It is located within Crater Lake National Park in southern Oregon.

Crater Lake is renowned as the deepest lake in the United States, reaching a depth of nearly 600 meters. It has no incoming rivers or streams, so its water is incredibly pure and free of mineral sediments, giving it an intense, striking blue color. It is considered one of the clearest and most pristine bodies of water in the world.

While naturally isolated, Crater Lake does have populations of rainbow trout and kokanee salmon, which were introduced by humans between 1888 and the mid-20th century. No stocking has occurred since 1941, yet the fish have sustained themselves through natural reproduction. Anglers are permitted to fish in the lake without a state fishing license.

Yes, you can swim in Crater Lake, but only in designated areas and for short periods due to the extremely cold water. The surface temperature rarely exceeds 15 degrees Celsius even in the peak of summer. The only legal and safe access point to the water's edge is via the steep Cleetwood Cove Trail.
