"Powder" is also used to describe the ultimate conditions for snowboarding, with a couple of meters worth of loose and ice-cold crystalized water. Is slower to ride in it than ice, obviously, but when the hill is steep, the smooth moves and countermoves feels like riding on silk. It also A LOT nicer to fall on when you try that 180 tailgrab that went wrong...

Use in common talk: "How was the conditions at Hemsedal"? "Oh, man! It was incredible! Powder all over the tracks!"
