Large natural on Cedar Mtn.

Date

Took a drive up and around the Yellowstone Club and saw this slide today. I think that is Cedar Mt with Pioneer Ridge in front and to the left. Stay safe out there.

Notes

From obs 1/29/23: "Noticed multiple crowns while driving up to bridger bowl this morning. Most evident was wide crown line on saddle peak below the corniced ridge stretching from the summit towards football field. Another was an obvious crown on what I believe is Argentina Bowl south of Saddle peak. From a distance, this all looked like new snow crowns and didn’t seem like anything stepped down to our buried weak layers. East wind had an interesting effect on the ridgeline above bridger bowl."

BBSP noted on 1/29/23: "A crown on Saddle Peak could be seen in today's bright light.  It began at the football field, extended to the top of the peak and a flank was visible extending down the skyline.  A secondary pocket pulled on the north facing slope below the Going Home Chute.  On the west side St Lawrence pulled out wall to wall, and behind Mountain Mother had a crown that was more filled in on the south facing side that began about half way down.  Also, a crown was noted on the south facing ridge of Bradley's Meadows ridge below the cliffs."

From 1/30-2/4 we also noticed old crowns "Between the Peaks" on Saddle, in the Y-couloir on the West side of Saddle Peak and in Jones creek on the west side.

Notes

I was skinning up the ramp on Friday when I thought I heard a jet flying over in the clouds, but the sound stopped instantly. I assumed that I heard an avalanche, but was solo on the ramp and had no desire to go that way for a better look.  It was snowing and foggy. Today a friend said she could see a crown on the north side of Wolverine bowl that appeared to be 4 feet. With all that water, I thought something would go deeper, eh?
