Colfax Peak (center) is an erosional remnant of Black Buttes volcano, a predecessor to Mount Baker that was active from about 500,000 to 300,000 years ago. Coleman Saddle (right center) divides the NE-dipping lavas of Black Buttes from Mount Baker, whose summit lies out of view to the upper right. Easton Glacier descends diagonally across the photo to the SW. Photo by Bill Chadwick, 1981 (U.S. Geological Survey).
