Location of Observation:
Widespread natural cycle in Huntington Ravine including below Harvard Bulge. 1-2’ x 200’ crown still visible just below the ice with chunky debris remaining visible low down almost to the floor. Old debris also visible below South, with small blocky debris on the floor. More eroded debris also just visible beneath Escape Hatch and possibly Odell,the first pitch ofwhich is fully buried in wind slab again. Ice in Central is covered with lots of snow filling the upper part of the gully as well as above the Fan. Approach to Pinnacle looks full of new sluff/wind slab. Northern gullies Low danger with snow mostly blown off or packed into stubborn looking slabs. Sastrugi high in other gullies and smooth wind slabs lower fit the profile for Moderate avalanche hazard with large wind slabs that will likely be stubborn to human trigger. Wind loading continues on gusts.
