Mount Mazama (Giiwas in the Native American language Klamath) is a complex volcano in the Oregon, United States, segment of the Cascade Volcanic Arc and Cascade Range that was pulverized when it erupted about 7,700 years ago. The volcano is in Klamath County, in the southern Cascades, 60 miles (97 km) north of the Oregon-California border. Its collapsed caldera holds Crater Lake, and the entire mountain is within Crater Lake National Park. Mount Mazama originally had an elevation of 12,000 feet (3,700 m), but since its climactic eruption Mazama now has an elevation of 8,157 feet (2,486 m). Crater Lake is 1,943 feet (592 m) deep, the deepest freshwater body in the US and the second deepest in North America after Great Slave Lake in Canada. Mount Mazama formed as a group of overlapping volcanic edifices such as shield volcanoes and small composite cones, becoming active intermittently until its climactic eruption. Mazama's caldera was created about 7,700 years ago by this enormous eruption, the largest within the Cascade Volcanic Arc in a million years. The eruption also destroyed Mazama's summit, reducing its approximate 12,000-foot (3,700 m) height by about 1 mile (1,600 m). Much of the edifice fell into the volcano's partially emptied neck and magma chamber. The region's tectonic plates are extending, making volcanic landforms and faults. Mazama is dormant, but the US Geological Survey says eruptions on a smaller scale are likely, which would pose a threat to the nearby surroundings. Indigenous people have inhabited the area around Mazama and Crater Lake for at least 10,000 years, and the volcano plays an important role in local folklore. White settlers first reached the region in the mid-19th century. Since the late 1800s, the area has been extensively studied by scientists for its geological phenomena and more recently for its potential sources of geothermal energy. Crater Lake and Mazama's remnants sustain diverse ecosystems, which are closely monitored by the National Park Service because of their remoteness and ecological importance. Recreational activities including hiking, biking, snowshoeing, fishing, and cross-country skiing are available, and during the summer, campgrounds and lodges at Crater Lake are open to visitors.
