Eleven of the thirteen volcanoes in the Cascade Range have erupted at least once in the past 4,000 years, and seven have done so in just the past 200 years. [21] The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21]
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 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 .
Mount Washington is a deeply eroded volcano in the Cascade Range of Oregon. It lies within Deschutes and Linn counties and is surrounded by the Mount Washington Wilderness area. Like the rest of the Oregon Cascades, Mount Washington was produced by the subduction of the oceanic Juan de Fuca tectonic plate under the continental North American ...
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.
Location in Oregon relative to other major volcanoes. The major landmark for the Rogue River Valley, [4] Mount McLoughlin reaches an elevation of 9,493 feet (2,893 m). [1] The tallest volcano in between Mount Shasta — located 70 miles (110 km) to the south [5] — and South Sister 120 miles (190 km) to the north, it lies in the Cascade Range, in the southern portion of the U.S. state of ...
Quaternary volcanic production rates in the Cascade Range from Jefferson to Crater Lake have averaged 0.72 to 1.44 cubic miles (3 to 6 km 3) per mile of arc length per million years. [44] In the area surrounding Mount Jefferson, monogenetic volcanoes constructed an upland area composed of basaltic lava flows and small volcanic vents.
