“I just want to ride powder,” Robin Van Gyn says. While her draw to the mountains is a simple one, her time spent up high is usually more complicated than the desire that got her there. In “Side Tracked By Full Moon,” the big-mountain mistress explains the importance of snow science and safety in relation to her expeditions into the alpine. For additional viewing pleasure, there’s clips of her riding some pretty big lines, too. And damn, Robin can rip.
