Mount Mazama, a complex of overlapping stratovolcanoes and shield volcanoes that was once one of Oregon's largest volcanoes, collapsed about 6850 years ago, forming the 8 x 10 km Crater Lake caldera. The clear blue lake fills a big hole caused when before 7700 years collapsed volcano peak. Mount Mazama was formed as a succession of overlapping cones and shields during a period of relatively continuous volcanic activity that lasted nearly half a million years, from about 420 to 40 ka.
The lake partly fills a nearly 2,148-foot (655-meter) deep caldera.The volcanic crater was formed by the collapse of the volcano, Mount Mazama, about 7,500 years ago. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. An informational presentation about Mount Mazama … The lake partly fills a nearly 2,148-foot-deep (655 m) caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama.
