The Cascade Arc includes nearly 20 major volcanoes, among a total of over 4,000 separate volcanic vents including numerous stratovolcanoes, shield volcanoes, lava domes, and cinder cones, along with a few isolated examples of rarer volcanic forms such as tuyas. Volcanism in the arc began about 37 million years ago; however, most of the present ...
This is a list of Cascade volcanoes, i.e. volcanoes formed as a result of subduction along the Cascadia subduction zone in the Pacific Northwest of North America. The volcanoes are listed from north to south, by province or state: British Columbia , Washington , Oregon , and California .

At an elevation of 14,179 ft (4,322 m), it is the second-highest peak in the Cascades and the fifth-highest in the state. Mount Shasta has an estimated volume of 85 cubic miles (350 cubic kilometers), which makes it the most voluminous volcano in the Cascade Volcanic Arc.
The High Cascades are the most recent volcanic arc in the Pacific Northwest, which forms the Cascade Volcanoes. These volcanoes, including the Three Sisters, were fed by magma chambers resulting from the subduction of the Juan de Fuca tectonic plate under the western edge of the North American tectonic plate.

Mount Hood, also known as Wy'east, is an active stratovolcano in the Cascade Range and is a member of the Cascade Volcanic Arc.It was formed by a subduction zone on the Pacific Coast and rests in the Pacific Northwest region of the United States.
The east side of Mount Baker in 2001. Sherman Crater is the deep depression south of the summit. Mount Baker (Nooksack: Kweq' Smánit; Lushootseed: təqʷubəʔ), [9] also known as Koma Kulshan or simply Kulshan, is a 10,781 ft (3,286 m) active [10] glacier-covered andesitic stratovolcano [4] in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States.
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as many of those in the North Cascades, and the notable volcanoes known as the High Cascades.
