Comments
5 or 6 turns down the Emma ridge that goes to the top of the Silver Fork Headwall, a soft wind slab cracked out and ran down the wide open gulley to the skier's left of the ridge. I knew the new snow was not bonded well with the sun crest and had lots of cracking in other spots during turns but this was the only one that ran. Visibility was not very good so only guessing how far it went based on the cloud I could see. I was surprised how far it went and how narrow it was. Hopefully these instabilities will settle out quickly.
