White Chuck Cinder Cone

White Chuck Cinder Cone is a volcanic formation in Snohomish County built from lava fragments ejected from a single vent opening. The cone rises to approximately 1834 meters and displays the characteristic conical shape created through repeated volcanic activity.

The volcanic formation developed several thousand years ago through explosive eruptions, with scientific analysis of glacial erosion suggesting an age between 2000 and 17000 years. Documentation of the formation as a distinct geological feature occurred in 1934, after which researchers began detailed study of its structure.

The Cascades Volcanological Observatory monitors this cinder cone as part of its research into volcanic activity in the North Cascades region.

The cone is accessible via established trails that allow visitors to view the volcanic landscape firsthand. The best time to visit is from early summer through early fall, when trails are clearer and easier to navigate.

The structure clearly shows how lava fragments of varying sizes accumulate gradually around a central vent. This natural buildup makes the cone a particularly instructive example of volcanic processes occurring in the region.
