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 ...
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]

Inundation zone I : Pathways for eruption-related lahars due to large flanks collapses or pyroclastic flows, or floods in the Skagit River valley cause by displacement water in reservoirs by lahars Inundation Zone II : Pathways of lahars resulting from more frequent, small-for-moderate flank collapses from the area of Sherman Crater.

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. All of the exceptionally large caldera-forming eruptions within the cascades erupted silica-rich magmas, with the three VEI 7s erupting mainly rhyodacite and rhyolite .
