Avalanche: Hatcher Pass

From a distance of about 1 mile west we observed a party of 4-5 snow machines riding among the boulders and high marking on a few slopes.
One of the riders worked up the west face of the ridge separating archangel creek and the little su. As the rider hit their high mark and traversed lookers left to a sub ridge they triggered a medium sized slab that ran 400’ or so. The rider reached the safety of the ridge feature and descended the path to the party below.
