The Cascade Range, or Cascades, is a major mountain range in western North America, stretching from southern British Columbia through Washington and Oregon to northern California. It consists of both non-volcanic mountains, like those in the North Cascades, and active volcanoes, notably the High Cascades. The part of the range in British Columbia is called the Canadian Cascades or Cascade Mountains locally. Mount Rainier in Washington is the highest peak in the range, standing at 14,411 feet (4,392 meters). The Cascades are part of the Pacific Ocean's Ring of Fire, a zone of volcanic activity around the Pacific Ocean. All volcanic eruptions in the contiguous United States over the last 200 years have occurred in the Cascade Volcanoes, with the most recent major eruptions being from Lassen Peak (1914-1921) and Mount St. Helens in 1980. Mount St. Helens has had minor eruptions as recently as 2004-2008. The Cascades are also part of the American Cordillera, a continuous chain of mountain ranges that runs through North, Central, and South America. The range is home to several national parks and protected areas, including North Cascades National Park, Mount Rainier National Park, Crater Lake National Park, and Lassen Volcanic National Park. The northern half of the Pacific Crest Trail runs along the range.
