I've actually spent a fair amount of time up in the Canadian Arctic, from Yukon Territory to Nunavut, and I count among my friends a number of Inuit people. I've asked them to verify that much-quoted "fact," and all I've ever gotten was a kind of knowing rolling of the eyes, as if to say, "maybe so, maybe not--but you're welcome to keep believing it!" So I still don't have any idea how many words they have for snow! (I've heard the number 52 quoted more than once.)
We skiers have quite a few ourselves, of course--snow, powder, ice, champagne, hardpack, bulletproof, death cookies, chicken heads, graupel, slush, sleet, breakable crust, windslab, corn, manmade, hail, hoar, frost, packed powder, bottomless, coral, crud, Sierra Cement, mashed potatoes, drifted, corduroy...to name a few--any others? (Perhaps we should start a running list!)
Avalanche specialists have a whole vocabulary of snow terms. If you want a real reference, you might start with avalanche information books and other resources.
