Snowboarder triggered avalanche east of WMR

While skiing inbounds at WMR I observed what appears to be a snowboarder triggered slab avalanche immediately east of WMR and west of the Half Moon slide path.

• The slide appears to have occurred today (2/20/19) on a steep convex rollover in or just below a cliff band on a west-southwest aspect. 
• Views of the debris and the majority of the slide were obstructed by trees.
• This was viewed from a distance with the size estimated and phone photos poor quality.
• The FAC has not heard from the Individual(s) involved in this incident so we do not have any further details as of now.
