Washington’s Second-Most Restless Volcano Deserves a Closer Look

ENUMCLAW, WA—Mount Rainier gets most of the attention around here, which is fair enough given that it dominates the eastern horizon on a clear day and is visible from nearly every high point in the foothills. But Washington State has more than one restless peak, and the one sitting about 150 miles to the north makes a compelling case for a second look.

Mount Baker, known to the Lummi and other Coast Salish peoples as Koma Kulshan, or simply Kulshan, rises to 10,781 feet in the North Cascades of Whatcom County, roughly 30 miles east of Bellingham. It is a glacier-covered andesitic stratovolcano, the same broad category as Rainier, and it belongs to the same Cascade Volcanic Arc that gives western Washington its particular combination of scenic grandeur and geological unease.

What separates Baker from the crowd is its thermal activity. It holds the second-most active crater in the entire Cascade Range, trailing only Mount St.

Helens. That ranking matters because St.

Helens earned its reputation the hard way in 1980. Baker has been comparatively quiet in recorded history, but geologists keep a close eye on it for good reason.

The mountain is also younger than it looks. 5 million years, but the current cone is estimated to be no more than 140,000 years old, and possibly as young as 80,000 to 90,000 years.

In geologic terms, that makes it practically new construction. Older volcanic formations in the area have been worn away by glaciation, leaving Baker standing as the youngest volcano in its own volcanic field.

For anyone who thinks of Enumclaw primarily in terms of Rainier’s shadow, the existence of Baker is a useful reminder that the whole region sits atop an arc of volcanic peaks stretching from northern California into British Columbia. The drama visible from a clear day in the foothills is not a local quirk.

It is part of a system, and Baker is one of its northern anchors. The mountain’s heavy glacier coverage made it an early subject of scientific interest and an enduring draw for climbers, painters, and photographers.

Albert Bierstadt captured it in 1891, which says something about how long people have been stopping to stare at it from a respectful distance. That, at least, is a habit Enumclaw residents should find immediately relatable.
