Avalanche Observations

Details

My ski partner triggered this small storm slab near the bottom the the "Big Trees" run on the northwest side of Gray Butte, at about 7,000 feet. This slide was harmless, but failed within the new storm snow. We didn't investigate further. Sorry for the crummy picture.
