On the ridge line up to Big Jim we saw two small natural avalanches that ran earlier in the day, NE aspect at roughly 5800ft. Group of 4 dropped NE aspect roller at 6200. Rider 2 triggered a 10”ish 80ft wind slab on his line and also remotely triggered a similar one on the adjacent slope. Rider 4 also triggered a 6”, 50ft wind slab. Both broke behind the riders and the riders were able to stay in front of them. Looks as though they ran on an earlier crust.
