Pemberton Ice Fields, British Columbia, Canada
This is the most incredible area I have ever been in my entire life. You simply cannot bring enough gas to ride where you want to ride on a powder day. On a regular basis you climb hills that are so long that your sled runs great at the bottom and barely runs at the top.
The ice field in the background of this picture is at least 10 miles long. It is so smooth and flat that you can do 80 mph for the entire length if you want.
