Human triggered avalanche near Bacon Rind

While driving to and from West Yellowstone today, I noticed what is potentially a skier/snowboarder-triggered avalanche on the east side of HWY 191 on a West/Southwesterly aspect, directly across the highway from the Bacon Rind Area and Snowslide Creek.  There were numerous tracks through steep rocky chutes next to the road, one of which had avalanched perhaps 75' wide, 18-24" deep, and running nearly to the flats at the base of the slope.  Judging by the thin layer of fresh snow it potentially happened on Sunday or maybe Monday.  There were tracks through the cliffs above the slide and coming out of the slide.
