Snow sliding downhill

Usually sliding downhill is so much fun. With the warmer daytime temperatures and colder nights the snow has turned into almost ice on top. Now that seems like you'll have a lot of fun sliding downhill but at this speeds and not being able to slow yourself down it can be very hazardous to your health when you started approaching the tree line at the bottom of the hill. Putting your hands down to slow yourself down have no effect when your hands are sliding across the icy surface.
