Drove through Turnagain Pass on our way to Summit Lake. Visibility was good from Center Ridge on South. We observed significant flagging and active wind loading along ridge tops. Could see evidence of mid storm crowns on North shoulder of Sunburst, SW face of Sunburst, Magnum West face (as noted yesterday,) Lipps W face (small pile of debris), S face of Lips – large filled in crown. Seattle Ridge East aspect – large piles of debris along most of the ridge (all noted in yesterday’s ob.) Could see new debris on North aspect of Twin in channeled terrain, but visibility was obscured towards Silvertip, Lynx, and Johnson Pass.
