The question haunted me, and the real answer came, as answers often do, not in the canyon but at an unlikely time and in an unexpected place, flying over the canyon at thirty thousand feet on my way to be a grandmother. My mind on other things, intending only to glance out, the exquisite smallness and delicacy of the river took me completely by surprise. In the hazy light of early morning, the canyon lay shrouded, the river flecked with glints of silver, reduced to a thin line of memory, blurred by a sudden realization that clouded my vision. The astonishing sense of connection with that river and canyon caught me completely unaware, and in a breath I understood the intense, protective loyalty so many people feel for the Colorado River in the Grand Canyon. It has to do with truth and beauty and love of this earth, the artifacts of a lifetime and the descant of a canyon wren at dawn.
