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.
During recorded history, eruptions at Mount Baker have mainly occurred from Sherman Crater. The earliest historical eruption took place in 1843, with more recent eruptions having occurred in 1852–1853, 1854, 1858, 1859–1860, 1863, 1870 and 1880. These eruptions ranked 2 and 3 on the Volcanic Explosivity Index. Possible but unconfirmed ...
Formation of the caldera about 1.149 [3] million years ago was accompanied by the largest eruption in the history of the Mount Baker volcanic field. [4] The eruption was subglacial, blasting upward through the continental ice sheet. [1] Over 124 km 3 [5] (29.7 cubic miles) of rhyodacite magma erupted from a shallow magma chamber in an ultra ...
The few eruptions that do form calderas rarely make it into the VEI 7 range, staying confined to the VEI 6 range in most cases. The only volcanoes known to have produced eruptions within the VEI 7 range are Crater Lake , the Mt. Baker Volcanic Field , and the Lassen Volcanic Center .
Mount Whitney is the highest mountain peak in the Sierra Nevada, the State of California, and the contiguous United States. This article comprises three sortable tables of major mountain peaks [a] of the U.S. State of California. The summit of a mountain or hill may be measured in three principal ways:
Mount St. Helens, once the fifth-tallest peak in Washington State, lost about 1,300 feet from its height of 9,677, according to the USGS. The highest part of the crater rim on the southwestern ...
A basaltic lava flow traveled down the Sulphur Creek valley and across the Baker River valley; this is the most recent lava flow at Mount Baker. [2] [3] Future eruptions from Schriebers Meadow Cone are unlikely to occur as it is considered a short-lived feature. [2]
A conifer forest will return to Mount St. Helens in its own time. On a debris-avalanche deposit totally devoid of life after May 18, 1980, plants are slowly taking hold of the landscape.
