Saw this slide today in my travels in Logan Dry. Did not get too close to it but it seemed to be a pretty deep repeater. I would assume it happened on Saturday during the storm or even more recently such as during the Sunday night strong east wind event. It does appear it failed near the ground and was rather deep, probably in the 3-4 ft range.

Avalanche depth, size, and running distance are estimates

From Erik Syrstad 2-2-16 (Thanks):

I think you are correct about timing. When I skied this shot on Sunday evening (from the trees on the left side of the photo, just after sunset), it was dead calm up there and no active wind loading was observed. The Ogden Peak station shows an east wind kicking up starting around 630-7 pm that night.

This is definitely a repeater. Pretty much all the big slide paths in the Logan Peak area and front canyons slid somewhere during or after the Christmas cycle. At one point almost everything I was skiing was a filled in bed surface including this one. However this one may have either gone twice, or not until later, with a smaller slide after New Year (maybe from that east wind event). On Jan. 9 it was basically dust on crust, with ~8” of beautiful snow on top of a hard bed surface, and lots of debris ~500’ below the ridge that was partially covered. Mogul run.
