Skied off the top of Marmot Ridge onto the N face. Started skiing right of the fall-line on one of those spiney ridges, and then cut skiers left to get on top of it, then the storm slab released. A section broke out, was not deep enough to carry me. I then continued cutting and another storm slab released. Avalanches stopped before the end of the couloir / apron.
Obvious signs of instability

Small natural avalanches from storm. New snow.
Light to no wind, mostly cloudy, below freezing on ridge tops.
A noticeable dense slab on top, definite wind loading, possible soft wind slabs. New snow was wet at the parking lot; progressively dried with elevation but still heavy at the ridge top.
