"If you go on some really big, really ambitious trip or you have some enormous goal, if you look at the big picture all the time, it's too intimidating, it's too big, it seems too insurmountable," says Jim Harris. "If you break it down into the next move, or the next pitch, or the next day of hiking, or the next rapid or whatever it is, those chunks are manageable. And there's a lot of aspects to spine injuries that are that same way." A year and a half ago, Jim traveled to Patagonia to attempt a 350-mile traverse of the Patagonian ice cap via kite-ski and packraft. But before the team even made it out of town, Jim was practicing with his kite when an errant gust of wind pulled him into the air and the slammed him back into the ground, breaking seven vertebrae and rendering him paralyzed. For the fifth installment of our Mileposts series, we travel to Grand Teton National Park to bring you a story of how much these places we love can take away from us, and about how, sometimes, those same places can teach us the skills we need to come back.
