Just got back from a helicopter flight to, over, and landing in the Grand Canyon. I have a bad track record with outings, but this was sublime (though I'm not sure if anyone could tell, as it was sublime in a manner that had me wrapped in my own headspace).
The Grand Canyon itself is, well, famously grand, but focusing so much on it does a great disservice to the surrounding landscape, which defies description. I was about to construct an analogy involving craftsmen and chisels, but to compare it to human art would be to do the country a disservice and to demean it: It was not carved, but magnificently eroded.
I would not have thought that a landscape so arid would be so shaped by waters, but the entire landscape was full of dry water-courses, canyons, and arroyos; there was little water to be seen, but its trace was everywhere. (Maybe this is because it is so arid, and the soil therefore contains much less organic matter to soak and bind up the water, so that when it does rain, it flows unimpeded?) It was interspersed with cliffs and hills and small mountains -- but never a rolling landscape. Rather, craggy ridges and scarps thrust into the air, seeming to defy geology. One hulking ridge was all rusty-red down one side (from, yes, rust), whereas the other crumbled away in a dark umber, nearly black. In places, ridges jutted up at forty-five degree angles, yet were banded with what for all the world looked like the bands of sedimentary layers. Were they sediments, and were those ridges thrust up tectonically? If not, what other process was responsible? In one place a stepped ridge was in at least four different colours, each step running along the ridge distinct -- the first white, the next yellow, then rust, and finally that dark umber.
Nor was it a dead landscape. Arid, yes, and probably that is why it is so geologically dramatic, because it is thus free of not one but two great sources of erosion, rainfall and organic factors; yet though the great part of the ground was bare and dry, still you'd never have been more than a few steps from a cactus, or spiny bush, or other plant (tough, dry, spiny, thick-leaved) that I cannot even categorise. I saw no animal life save flies, a crow, and a few sea-birds on Lake Meade (which barely counts), but there was a ubiquitous buzz of insects. Somehow this appealed to me even more in some ways than a forest (though I do love to walk in a forest), perhaps because it seemed comprehensible. I don't know the few dozen important plant species, nor yet the insects and many lizards and so on, but in this arid and therefore sparser, slower-moving ecosystem, it had an air, it looked as though one might with study figure it out -- not like even a temperate forest, where I wouldn't even care to guess the order of magnitude of the number of important species. This isn't to say that I dislike a forest just because its ecosystem is too far beyond my grasp, but rather that the lure of attainable comprehension was another attraction of the desert.
