Synopsis:

Three snowmachiners were caught in an avalanche triggered by the party. Two were caught and carried while the third was overrun by debris as he sat on his snowmachine at the base of the slope. Of the two riders caught and carried, one came to rest on the surface uninjured and the other was shallowly buried but killed, likely from trauma. The third member of the party was partially buried (to his waist) and able to eventually dig himself out.
