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 .
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 ...
Medicine Lake Volcano — a shield volcano in northern California which is the largest volcano by volume in the Cascades. Mount Shasta (northern California) — second highest peak in the Cascades. Can be seen in the Sacramento Valley as far as 140 mi (230 km) away, as it is a dominating feature of the region.
Then, on May 18, 1980, the dramatic eruption of Mount St. Helens shattered the quiet and brought the world's attention to the range. Geologists were also concerned that the St. Helens eruption was a sign that long-dormant Cascade volcanoes might become active once more, as in the period from 1800 to 1857 when a total of eight erupted.
The Cascade volcanoes are part of the Pacific Ring of Fire that includes over 160 active volcanoes. Articles listed under this category should be cross-listed under the correct geographical categories too. For mountain range categories, the appropriate choices are Category:Cascade Range or Category:Pacific Ranges.

Two people in Thomas J. Dryer's 1854 expedition calculated the elevation to be 18,361 ft (5,596 m) and the tree line to be at 11,250 ft (3,430 m). Two months later, a Mr. Belden claimed to have climbed the mountain during a hunting trip and determined it to be 19,400 ft (5,900 m) upon which "pores oozed blood, eyes bled, and blood rushed from ...
Located about 25 miles (40 km) north of Adams is Goat Rocks Wilderness and the heavily eroded ruins of a stratovolcano that is much older than Adams. Unlike Adams, the Goat Rocks volcano was periodically explosive and deposited ash 2.5 million years ago that later solidified into 2,100-foot (640 m) thick tuff layers. [34]
