Avalanche: Hatcher Pass
Location: Marmot, South Ridge
This was an avalanche reported to HPAC today by a person who interviewed the party who triggered the avalanche
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.
