Crater Lake was formed after the collapse of an ancient volcano, posthumously named Mount Mazama. This volcano violently erupted approximately 7700 years ago. That eruption was 42 times as powerful as the 1980 eruption of Mount St. Helens. The basin or caldera was formed after the top 5000 feet of the volcano collapsed. Subsequent lava flows sealed the bottom, allowing the caldera to fill with approximately 4.6 trillion gallons of water from rainfall and snow melt, to create the seventh deepest lake in the world at 1,932 feet.
Crater Lake National Park is host to a diverse array of activities. While enjoying the natural scenic wonders, park visitors may hike in old growth forests, participate in a variety of interpretive activities, camp out or stay in an historic hotel, or even cross-country ski during the eight month long winters which are experienced here in the high Cascades.
