Red Flags Comments
Despite glassing much of the north side of Timpanogos, the northeast side of Box Elder, and the east side of the White Baldy Wishbone Ridge, we did not see evidence of widespread avalanche activity from last weekend. Perhaps crowns have blown in, but we did not see much in the way of old debris piles either. No cracking or collapsing noted.
