North east side of Pfeifferhorn Peak in the afternoon sun. Then wrapped around to the north west side as well.
This photo was a slab avalanche that pulled out a few days ago I would assume. There was a significant amount of debris in the runout of the Needle from this avalanche (debris was 10 -15 ft deep). It also appeared to have triggered another piece of snow on a lower flank as well.
Not sure on the weak layer, I did find shallow places with faceted snow on the way up the needle especially around rocks. As you can see in the photo this avalanche broke on a steep slope that was rocky. However, its hard to say if it actually was faceted snow or the hardness change in the recent storm layers.
Another and more significant avalanche was noted on the east face of Lone Peak, in the apron. This looked to be more recent, probably yesterday with the high rain/snow line. It was a big avalanche that likely failed on old faceted snow, It was roughly 300 ft wide 2-5 feet deep would be my guess.
It was flat light and windy so I didn't take out the camera. Thanks to wasatchbackcountryskiing.com map I can draw in the rough estimates.
Just in case you want to go there, don't forget to bring a rope and save some energy for the wicked down climbing on snow and ice covered boulders to get out.
