Surface for skiing (4)

Ross

I believe the answer is:

snow

(Other definitions for snow that I've seen before include "Jon - - (Ch.4 News)" , "Wintery precipitation" , "Precipitation in the form of ice crystals" , "that may come at Christmas" , "It falls in flakes" .)

I've seen this clue in the Newsday.com, the Newsday and the USA Today.
