Complete Deadly Descent: Avalanche in Alaska, Denali - Emergency Exit without the use of armor. If you have not previously completed this event you will be using Psymon.
For this descent your camera will be reversed and actions such as landing a jump or making a sharp turn will start snow balls rolling down the hill(Avalanche). This is one of the few descents where speed is your friend as you will need to outrun the avalanche so it is a good idea to hit Tricky/Super Tricky as soon as possible and maintain it. The snow balls gather speed as they travel down the hill and will do damage to you, and if there are enough, they can knock you over. When you start the run you'll have a few dozen meters to build up your boost without having to worry about avalanches; the snow's solid at the top. Listening to the Helicopter pilot is also useful, as she'll say things like "There's a crevasse on your left, stay to the right." These messages also appear written on the snow in huge letters, and all of these refer to the players direction, for example when they say "Stay Left", it means the left side of your screen, not in reference to which way your character is moving/facing.
