Gnar pow is when a region gets completely shit on with a snow storm. We combine the words Gnarly and Powder. Gnarly meaning over the top and extreme with powder, which is high amounts of fallen snow.
"Holy crap look at the gnar pow! I can't wait to shred!"

When the lord above rains down with the white fluffy stuff till it's creepin' on your nether regions.
So we hit the back bowls at A-Basin yesterday and shredded some of the gnar pow.
