In October elite snowboarders from all over the world come to Saas Fee, Switzerland, to start their winter season at a high altitude snow park with big jumps and a large halfpipe. While Marcopoulos was there to make a video with American Olympian Lucas Foster, he met and photographed other riders like Japanese Olympic gold medallist Ayumu Hirano, his brother Kaishu, famed for performing the highest air ever in competition, and the Korean Chaeun Lee, who later in the season became world champion halfpipe at age 16. The video and this book are both titled Butter; a word the riders use when a trick is performed smoothly with a lot of personal style.
