Zone or Region:
Within the crater on Mt St Helens.
Did you observe any avalanches? Yes
Size 2: Could bury, injure, or kill a person
Large avalanches on very high angle slopes within the Mt St Helens crater. Not publicly accessible area.
It is unusual to see large slides on these very steep (60 degree) slopes. The size is difficult to judge at this distance, but these are at least D2. It looks like they ran on Saturday 10/30.
