“ I do not know, really, how we will survive without places like the Inner Gorge of the Grand Canyon to visit. Once in a lifetime, even, is enough. To feel the stripping down, an ebb of the press of conventional time, a radical change of proportion, an unspoken respect for others that elicits keen emotional pleasure, a quick intimate pounding of the heart.The living of life, any life, involves great and private pain, much of which we share with no one. In such places as the Inner Gorge the pain trails away from us. It is not so quiet there or so removed that you can hear yourself think, that you would even wish to; that comes later. You can hear your heart beat. That comes first. ”
