The Cascade Range contains Mount Shasta, a prominent volcanic peak in northern California.
Mount Shasta rises to 4,322 metres and is one of the tallest volcanoes in the United States. It is a stratovolcano built from overlapping volcanic cones, and its snow-covered profile has made it a major landmark of the southern Cascades. Shasta is not currently erupting, but it remains classified as an active volcano because it has erupted during the Holocene.
The Cascade Range extends from northern California through Oregon and Washington into British Columbia. It forms part of the Pacific Ring of Fire and includes many volcanoes, such as Mount St. Helens, Mount Rainier, Mount Hood, and Lassen Peak.
Mount Shasta is sometimes assigned to the nearby Klamath Mountains because of regional geography and ecological transitions. In the standard volcanic and tectonic classification, however, it is a Cascade volcano. The Sierra Nevada lies farther east and is a separate range.
