Professional skiing on the slopes of Alaska

A book by Takafumi Konishi (Rome Snowboards, Columbia) in Alaska.
It is because of the professional rider who has abundant experience in the mountains of the world that the steep slope exceeding 40 degrees, the gliding distance and altitude difference where the bottom looks much smaller, and the undulating and stylish air that can not be seen ahead can be created.
It would be great if you could slide freely while playing the terrain like this.
