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 ...

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. Lassen Peak (south of Mount Shasta) — southernmost volcano in the Cascades and the most easily climbed peak in the Cascades. It erupted from 1914 to 1921 ...
Mount Mazama (Klamath: Tum-sum-ne [5]) is a complex volcano in the western U.S. state of Oregon, in a segment of the Cascade Volcanic Arc and Cascade Range.The volcano is in Klamath County, in the southern Cascades, 60 miles (97 km) north of the Oregon–California border.
Three Fingered Jack is a summit of a shield volcano of the Cascade Range in the U.S. state of Oregon.Formed during the Pleistocene epoch, the mountain consists mainly of basaltic andesite lava and was heavily glaciated in the past.
Its summit is the highest point within Crater Lake National Park, and the tenth highest peak in the Oregon Cascades. [6] A small fire lookout tower stands on the summit, at the end of a trail that zigzags approximately 1,500 feet (460 m) up the mountain. The mountain is named for Oregon pioneer Levi Scott, founder of Scottsburg, Oregon. [7]
