Our group of nine climbers summitted Mt Baker in Washington's North Cascades mountain range. Near the summit, we stopped for a break at which time I videotaped and recorded the sound eminating from its crater.
The hissing sound originates from the crater whereas the roaring sound is the wind.

Steph Abegg sent us several aerial views into Sherman Crater taken on February 26. John Scurlock piloted the plane. The photos show once again that even in the depths of winter, fumarolic heat flow is sufficient to keep a fair amount of the talus and rock in the fumarole fields bare of snow.
