This is a second hand report on the previously reported incident submitted today, which is now confirmed as snowboarder-triggered. I was not involved in the incident nor onsite, but sharing knowledge here for others, as gathered via the TAY FB discussion. Video shared here of a snowboarder triggered partial burial https://www.instagram.com/tv/CNVP1gYDZd_/?igshid=13pdhtvoyc2mr&fbclid=IwAR0mwFG5AF2jjJ33_KXR_VMNFvHIICOIyC2KB6jF3iGmCuz6Sn7AGoqQ9UwPhoto:

Observations
here is the information provided on TAY of the observing party:
Even though avalanche forecast has been 'green' for 'west slopes south', on Mt. St. Helens April 7 we observed a recent large slide several hundred feet wide/long with lots of debris near the bottom (enough to bury a person) that started off a steep SE facing section of Monitor ridge to the west of the main hiking route which showed a deep crown (which is not a typical wet slide feature) below the cornice. There were tracks near it, suggesting it could have been triggered by skiers/snowboarders over the past few days.
