Baker geology

Volcanic ash in a trail cut along the Park Butte trail, just west of the trail fork to Railroad Grade. The BA is the dark layer below the vegetation. The orange layer is another Baker tephra, OP, which resulted from a ‘throat clearing’ steam blast at Sherman Crater just before the magmatic BA was erupted. A dark soil layer separates OP from the thin white layer, Layer O ash from Crater Lake caldera (Mount Mazama). Glacial till is at the bottom.

Volcanic ash deposits and volcanic bombs from Mount Baker (2 articles).

Large debris flows that descend Boulder Glacier occur periodically. These are a potential mortal danger to climbers.

Reports of research funded by MBVRC grants are here.

A historic 1912 photo from Loomis Mountain by J.D. Welsh shows the entire south flank of the volcano, and the exact duplicate 2012 photo by John Scurlock showing glacial changes.
