We were traveling along the MacDonalds ridge when this avalanche occurred naturally. We were well past the area that slid so it was definitely not remotely triggered by us. It appeared to be caused by the heavy winds which had loaded snow under the cliff band above. The slide ran into the gully, to the flats. Certainly not something you would have wanted to be a part of. There were no other parties in the area. We reported to Alta Central and spoke with canyons ski patrol once we had exited the area.
