snow at very cold temps generates more friction. it is so cold that the extremely thin liquidation that occurs from a ski on the snow surface can't happen, so you get even more drag. Cold ass snow is basically just millions of sharp little crystals slowing your shit down. Also the groomed right now is groomed fresh, so the snow is comprised of sharper crystals, and there is more air in the snow, consequently causing more friction. That is partially why the park is slow. Should be slightly faster tomorrow even though it'll still be wicked cold.
