Analysing terrain data
From the top of peak 10, take the south side gate and follow the ropeline until you see the steep dip down to the left, where you will see the very large roller known as "Mustang Booter".
This will signify your entry into the double black, expert only terrain of Mustang.
This run starts steep, then gets very flat, so keep your speed up on the first pitch.
Then it will be a nice and mellow run down that typically has great snow, but can be variable due to south facing, high sun exposure aspects.
