Group of three remotely triggered this large wind slab from about 800 feet away, while skiing the main SE bowl off the south ridge of Beaver Mountain. We had identified a broad, steep rollover on the skier's right side of the bowl as a problem area and chose to descend the far skier's left side of the bowl. I skied first, and at about 8000' noticed a very long crack propagating to the south. About 10 seconds later I saw a large powder cloud racing down the south side of the bowl, very far to the skier's right of my line. On our way back down to Franklin Basin, we had improved visibility and were able to check out the crown, which averaged a bit over 2 feet deep. The bed surface was a prominent sun crust, likely formed Saturday.
