Patagonia presents “Dirt Magic,” a Teton Gravity Research and Freehub Magazine film documenting Downieville, CA’s journey from dying mining town to mountain-bike mecca. Inspired by a desire to save their home trails, shaped by a grassroot organization’s unintentional stewardship, and fueled by the sport’s rowdiest festival, Downieville’s newest dirt miners are using that reputation to create a model community for struggling mountain towns across the globe—and it all started with a van, a chainsaw, and a few maxed-out credit cards.
