Since he started riding as a kid in New England, Jones has been at the forefront of nearly every revolution in snowboarding. It was 42-year-old Jones who first brought a full-speed, race-inspired style to 50-degree Alaskan slopes and 100-foot cliffs. It was Jones who, in an era when most stars used helicopters, ditched the fuel-guzzling lifts in favor of earning his turns by climbing up big peaks. It was Jones who popularized human-powered split-boarding as a way to hike up hills, via Jones Snowboards. And it was Jones who, in 2007, founded Protect Our Winters to bring awareness to climate change — well before athlete activism was cool. But it's always been his riding that's defined him. This includes an expedition to a 21,000-foot Himalayan peak that Jones became the first to summit — and the first to ride down its sheer snow spines. The feat was one of the hardest round trips anyone has ever lived through. In short: "He has shaped big-mountain snowboarding like no one else," says rider Xavier de le Rue.
