A multi-part series on the Grand Canyon as seen from its river

Of course, it’s not going to be about splashy adventures, near misses and honest-to-god mishaps, nor the eight hardy and idiosyncratic souls in our little troupe, or 23 nights spent sleeping on the ground. It’s going to be about rocks. Time and rocks. Water, time, and rocks, because after 22 days, 280 river miles, and some 160 rapids, I learned that the Grand Canyon is mostly about rock, and having the rare opportunity to immerse yourself in Earth’s ancient past. And as such, a Grand Canyon Expedition extends far beyond just what’s at the surface.
