Ringkasan geologi
Mount Baker is a glacier-covered andesitic stratovolcano constructed above the E flank of the eroded mid-Pleistocene Black Buttes volcano and SW of the early Pleistocene 4.5 x 8 km rhyodacitic Kulshan caldera. With the exception of the Schreibers Meadow cinder cone on the SE flank, which formed about 9,800 years ago, Holocene volcanism has been confined to the central conduit. A major eruption about 6,500 years ago, its largest eruptive event during the Holocene, was accompanied by a collapse that sent lahars down the Nooksack drainage. Residents in the Puget Sound region as far away as Victoria, British Columbia, observed 19th-century activity, all of which consisted of relatively minor phreatic eruptions. Sherman Crater, the crater immediately south of the summit, has been the site of increased steam emission since 1975. The Nooksack Indian Tribe referred to the volcano as Kweq Smaenit (the White Mountain), while the Lummi Nation knows it as Koma Kulshan.
Ringkasan Wikipedia
Ringkasan InggrisMount Baker, also known as Koma Kulshan or simply Kulshan, is a 10,781-foot (3,286 m) active glacier-covered andesitic stratovolcano in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States. Mount Baker has the second-most thermally active crater in the Cascade Range after Mount St. Helens. About 30 miles (48 km) due east of the city of Bellingham, Whatcom County, Mount Baker is the youngest volcano in the Mount Baker volcanic field. While volcanism has persisted here for some 1.5 million years, the current volcanic cone is likely no more than 140,000 years old, and possibly no older than 80–90,000 years. Older volcanic edifices have mostly eroded away due to glaciation.
