Natural avalanche at Blue Lakes

Pics came from a friend riding at Blue Lakes today. He thinks it was a natural trigger, and appeared recent, with a minimal dusting of new snow on the debris. Possibly 2/5/19? Looks to be at least a D2.

Pic 1: Note the debris still appears fairly fresh and has some fall-line scarring

Pic 2: Crown appears to be a "step down" 

Pic 3: Debris crossed a relatively flat section of the path and continued onto the next pitch
