The north flank of Mount Baker towers above Cockscomb Ridge, with the Roosevelt Glacier descending from the summit. The Dole Fumarole Field on the northern flank is located below a point around halfway down the left-hand horizon, near where the shadow line on the Mazama Glacier (center) takes a sharp bend. William Henry Dorr reported vapor emission at this location in 1884 and fumarolic activity continues today.
