Went for a walk and some turns on the north ridge of Dry Canyon. Upon gaining the ridge to Logan Peak we saw some very recent avalanches dropping north into the Logan Canyon side of the divide. Hypothesis: this week's storm snow and wind were the straws that loaded up the ridge and broke the camel's back. Looked to be post-thaw-freeze cycle. Grabbed photos of two independent, large slides and saw a third, but couldn't safely get good looks at any of them. All dimensions are estimates. Note crowns in foreground and background of first photo.

Forecaster's Comment's: Nate, thanks for the observation. These are certainly significant avalanches. But, I think at least some of the activity you describe was observed earlier in the week from near the summit of Logan Peak; see the observation......HERE If so, we think the avalanches occurred on the 15th along with many other slopes in the area.
