For three weeks we drift down the Colorado. The Grand Canyon is so large as to take hours to approach by car. Finding the flat space at Lees Ferry where we launch our boats feels very random, and I wonder how the first explorers managed. So many miles of walking or riding to reach this place, and so hidden from view. How many ridges had they crested looking for a way to the river before discovering this one?

Our days are nothing like theirs must have been. Our route is well planned and food precisely proportioned. We cook in crews and camp at spots long favored by the elders of our group. We stop for hikes to waterfalls that pour into the canyon, and stand in them, letting the cleaner, warmer water wash and refresh. It is a hundred and ten degrees in Arizona in August, and we are often in the sun.

Mostly a passenger, I spend some part of every day with my feet up and my hat over my eyes, watching a narrow sliver of river and sky without a care. It is peaceful, to be rowed, though less so to row, and several of our party eat ravenously every day. I manage to read three books, mostly in the quiet hours after camp is made, on nights when I am not responsible for the cooking. It’s a beautiful scene, to look up from one’s book and see the canyon walls rise high into the distance, or to see the river wind away into the sunset. For three weeks any conversation can be interrupted by “wow, look at that,” and everyone will. Condors, mountain sheep, hawks, herons, and frogs cause these exclamations, as do waterfalls, landslide evidence, and the cliffs themselves as we wind through one type of rock into another of a far earlier era.

So often the canyon reveals beauty in hidden spots. These side hikes, hidden caverns, or waterfalls are a surprise, the beauty of place that is invisible from without. The grandeur, the huge vistas and towering walls that sprawl across the horizon is overwhelming and an excellent reminder of real scale. These giant vistas have been photographed though, and can be seen in some sense from the rim, from above. The small canyons, etched by water in oddly smooth curves, with pools in between small waterfalls, that can be swam in or sat beneath, are impossible to discover any other way. They can only be found from the river.

And so for three weeks these small discoveries keep us climbing, hiking, and sweating, up hills and over cliffs, looking for another beautiful spot that takes work to find.
