Timeline for eruptions at Mount Baker during the Holocene (12,000 years ago to present).

No date exists for this photograph, but the image is likely circa 1900. Note the postcard copyright date of 1903.

Mount Baker's crater lake in 1976 formed due to glacial and snow melt as a result of increased heat from magma beneath the surface. Fumarole on left ejecting gas at a velocity of 268 kph (167 mph).

Geothermal ice cave at Mount Baker's summit formed by melting of a glacier due to increased heat from subsurface magma and fumarole on the surface expelling hot gasses.

Boulder Creek leading from Mount Baker, Washington is a hydrology monitoring site where water is collected and measured for chemicals that may signal volcanic unrest.
