Mount Baker (Lummi: Qwú’mə Kwəlshéːn; Nooksack: Kw’eq Smaenit or Kwelshán), also known as Koma Kulshan or simply Kulshan, is an active glaciated andesitic stratovolcano [4] 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 Saint Helens.[10] About 31 miles (50 km)[11] due east of the city of Bellingham, Whatcom County, Mount Baker is the youngest volcano in the Mount Baker volcanic field.[5] While volcanism has persisted here for some 1.5 million years, the current glaciated 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.
