Snowmobiler triggered avalanche north of Crown Butte

A snowmobiler triggered an avalanche (yellow pin) north of Crown Butte (the gray mountain at the top of the image). This zone is typically approached from Lulu Pass. His sled was partially buried, but the rider was not. Lots of new snow in the last 24 hours created a CONSIDERABLE avalanche danger.
