A pioneering big-mountain snowboarder and snowboard designer. (Not to be confused with snowboarding’s other Jeremy Jones, a luminary in the urban-jib scene.) Jones raced as a teenager in Maine, then switched to big-mountain riding after failing to make the 1998 Olympic team. He made a name for himself helicoptering onto Alaskan peaks and sending enormous lines while being filmed by Teton Gravity Research (cofounded by his two brothers). Burnout and concern for the environment led him to swear off copters and chairlifts in 2009, when he founded Jones Snowboards to produce splitboards, which can be separated into two pieces for uphill use. In 2007, he founded Protect Our Winters, a nonprofit that lobbies the snow-sports industry to address climate change.
