Clemina Creek Hillclimb avalanche

Clemina Creek area known as hillclimb. Unsure of trigger suspect windloading due to strong transport sw winds. Very long propagation up to 3m slab thickness. Suspect weak basal snowpack is finally at tipping point due to warming temps. Suspect time of release approximately 1pm as soon as clouds parted. Debris traveled far over a well used alpine route to access terrain. Third party info from a very trusting source.
