Minutes after we started hiking down the Grand Canyon’s South Kaibab Trail, we descended through short, tight switchbacks where the trail clings to the face of a cliff. The earth dropped away precipitously beyond the trail’s edge; we gazed down nearly a vertical mile into the bottom of The Big Ditch. Not much farther along, we stopped, awestruck, at a breathtaking overlook of perhaps the most famous canyon on the planet.
Those first vistas laid bare the audacity of our plans: to walk across this awesome chasm in one push, on a 21-mile, nearly 11,000-vertical-foot, rim-to-rim dayhike.
