An aerial photo of Mt. Baker in Washington State.Mount Baker was well-known to indigenous people of the Pacific Northwest. Indigenous names for the mountain include Koma Kulshan or Kulshan. Mount Baker 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. It is about 31 miles (50 km) due east of the city of Bellingham, Whatcom County, making it the northernmost volcano in the Cascade Range but not the northernmost of the Cascade Volcanic Arc, which extends north into the Coast Mountains. 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. At 10,778 feet (3,285 m), it is the fourth-highest mountain in Washington State and the sixth-highest in the Cascade Range. Located in the Mount Baker Wilderness, it is visible from much of Greater Victoria, Greater Vancouver and south to Seattle in Washington.
