Observation: Turnagain
Location: Road Obs
Drove through Turnagain Pass between 12:00 – 2:00pm looking for recent activity with the past three days of stormy weather. The 1-2′ of storm snow fell on a layer of surface hoar, buried on MLK Jr. Day (1/21). Found evidence of natural avalanches on the Southern end of Seattle Ridge (debris and filled in crowns).
Obvious signs of instability
Observer Comments
Four to five D1-D2 small slab avalanches on the Southern end of Seattle Ridge, most witnessed crowns were within gully features, or beneath previous wind features - not along ridge crest.
No obvious activity on the non-motorized side with the limited visibility.
