Avalanche Details

Hikers on the south ridge of Marmot were reported to have decided that they should go no further and descend. While descending and traversing along the top of a bench searching for a route down, they triggered an avalanche from above. No one caught.
They were hiking in an area that had a recent avalanche on Friday, on the same aspect as they were, on the pitch above them. See photos.
Picture shows a second group of hikers following the first group's tracks (who triggered the avalanche) from earlier in the day.
