What is the worst blizzard in history?

The Great Blizzard of 1888 was a huge whopper, but so was Snowmadgeddon. I mean, those too nearly covered us all up with snow! Luckily, I decided to close my wrath and end my blizzard. You're lucky I did spare you, mortals, from my icy wrath!
Anyway, I'd say Snowmadgeddon was worse than the Great Blizzard of 1888, but neither are anything to sneeze at.
