This is an avalanche that I triggered while walking the ridge above Days Fork. I was just minding my own business when I got a coll

Here is the second slide. The crown face is around 4 feet deep here.

Some skiers had skied the adjacent slope just to the west of the slide not long before I released it. This slide covered up tracks low on the slope. Interestingly enough, I randomly spoke with one of the people that skied the slope. There was very interesting descision making taking place prior to skiing the slope. It was their intention to ski south facing slopes for the day which were much more likely to be stable. Once gaining the ridge the lure of the north facing powder clouded their judgement and they skied into Days Fork luckly without incident. They then climbed back out to the north and experienced collapsing once they were nearing the ridge again. This is a sure sign of an unstable slope and it's my opinion that they narrowly avoided a serious avalanche accident. Once I told the person of the slide I triggered, I said he immediately felt sick to his stomach and that it will take some time to sort through his decision making. Again, thanks to the honest account which will help our community of backcountry users make better descisions.
