Global Volcanism Program | Image GVP-02732
This view from the SW shows the Deming Glacier below Lincoln (left) and Colfax Peaks, which are remnants of the Pleistocene Black Buttes volcano that once stood where Mount Baker is now. Lavas from Black Buttes, which was active from about 500,000 to 300,000 years ago, dip towards Mount Baker with its flat-topped summit (upper right). Easton Glacier is on the S flank.
