Several natural avalanches were spotted primarily on the north-facing terrain in Bagley Basin. A few were also seen on the west-facing slopes off Table Mountain facing Iceberg Lake. One of those may have been triggered by climbers, as reported in one observation: https://nwac.us/public-obs/17968/ There was also a treebomb triggered avalanche on The Arm. Most of these avalanches occurred in the early morning hours of 1/10/23 as the storm was coming to a close.
