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 in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States. It is the second-most active volcano in the range after Mount Saint Helens. About 31 miles (50 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 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.
FYI, the high-altitude 747 jetliner pix was taken by Pete Peterson w/his Canon 5D-Mark II using Mark Stadler's "Big Bertha" 500mm telephoto lens. Pix of Pete, Mark and BB are also in this Gallery.
