Comments
Wind event Friday January 18th. Saturday AM we noticed a large slide off International Mountain. We skied up to a col near there and noticed three distinct crown lines. It had been triggered near the summit, second and largest crown below the steep rock bands and a third crown appeared to show a step down exposing rocks.
