Ha ha, definitely “roofalanch”. The snow has built up on the lee side, actually accentuated by the wind. Note the near side of the hotel roof in the distance is windswept bare, but look close and the lee side just visible to the left of the chimney has drifted deep. Slid off the station roof, knocked a lot of the icicles off, and a pile of snow even remains on the door overhang - which is why the overhang was built.
Just the thoughts of a Canuck who has never seen snow
Cheers all,
