The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.
Mount Scott first erupted about 420,000 years ago and is one of the oldest volcanoes in the Mount Mazama complex. [8] [9] It erupted mainly andesitic lavas before becoming extinct in the late Pleistocene. [10] Since it was relatively far away from the main flanks of Mount Mazama, it survived the mountain's massive explosion that occurred around ...
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.
On a clear day from the summit, other visible volcanoes in the Cascade Range include: Mount Rainier, Mount Baker, and Glacier Peak to the north, as well as Mount St. Helens to the west, all in Washington; and Mount Hood, Mount Jefferson, and the Three Sisters, all to the south in Oregon.
The Juan de Fuca tectonic plate is being subducted under the North American Plate, leading to volcanic activity in the Cascades like at West Crater. In southern Washington state, the Cascade Range, which sits south of the dacitic Garibaldi Volcanic Belt, spans 600 miles (970 km) from British Columbia in Canada to Lassen Peak in northern California in the United States.
