I triggered a Slide on dorothy at about 6500' on a south aspect.The crown was 24" deep and 150' wide. Luckily I was able to ride out of it but looked to be about d2 in size. We also remotely triggered a small slide while skinning on a south east aspect. Still pretty touchy out there.
Further details from one rider involved:
we headed out to Dorothy, 4 experienced people in their 40's (3 splitboarders 1 skier), and first skied a skooks face run. We saw no signs of instability until we skied about 300' into the skiers right side of Dorothy from below the summit. There were no signs of other ski tracks on Dorothy. On the skin back up we heard 2 small whoomfs and then a bigger one once we got to the ridge. We triggered a remote slide at that point on a SE aspect. It looked pretty small and slow from where we were and we probably should have retreated to Skooks at that point. Later, we saw it was like 3 small slides we triggered from the ridge. We tried to descend skiers right Dorothy and avoid the guts. We did not trend right enough. We skied in a leap frog style and I, a splitboarder, was the last off the top but the first into the steep complex terrain. Just before I got to the steep terrain the snow fractured around me and I decided to point it slightly skiers left and was able to ride out of it. No one was carried at all. I quickly radioed up to the 3 above's relief. When I radioed I saw the avalanche coming down off to my right. I was safe but wanted to ride down to a safer spot to wait for the rest of the party to traverse right. Thank goodness we had radios. The rider behind me saw it break about 15' in front of him. He is the one who gave me the crown size. There are definitely convex and rocky areas around where I triggered it. Similarly the remote trigger from the skin track was around some rocky terrain.
I should note that it definitely took some riding to get out of the avalanche. It was not like I just pulled off to the side....Pretty scary stuff. I was lucky to ride out of it. The experience will lead to a little more conservative decision making.
