Mount Mazama was a stratovolcano that stood approximately 12,000 feet tall before it collapsed around 7,700 years ago, forming Crater Lake.
The caldera was formed when Mount Mazama erupted and collapsed, creating a basin that eventually filled with water to become Crater Lake, the deepest lake in the United States.
Wizard Island is a volcanic cinder cone that emerged after Mount Mazama's collapse, and it rises about 755 feet above the lake's surface.
Crater Lake is known for its remarkable clarity, with visibility often exceeding 100 feet, due to the lack of incoming streams and sediment.
Submerged trees, preserved by the cold water, have been found in the lake, some dating back over 7,000 years, providing insights into the region's climate history.
The Klamath tribes have long held Mount Mazama and Crater Lake as sacred, with oral histories recounting the eruption and formation of the lake.
The lake's deep blue color is due to its depth and purity, which allows sunlight to penetrate deeply and scatter blue wavelengths.
Mount Mazama is part of the Cascade Volcanic Arc, which includes other notable volcanoes like Mount St. Helens and Mount Rainier.
