More detailed information about the avalanche: 

We received a number of reports of natural and human triggered avalanches in the southern Whitefish Range that occurred over the weekend of January 23 and 24.  We investigated 2 of these that were within a few hundred yards of Flower Point.  Both avalanches were east facing, just below ridge line elevation, failed in the recent storm snow and had crown depths of 8-10".  One avalanche was a natural and the other was triggered by a skier.  Despite being relatively small in size both had the power to knock a rider off their feet which would then make them susceptible to being pushed into large trees and tree wells.
