Clicking on the picture above will take you on a slideshow tour of the Grand Canyon, shot from the right side of an LAX-bound 757 that departed from Boston. I have no idea what movie was showing at the time; though I do know I refused, as I usually do, to close my windowshade to reduce ambient light on the ancient crappy ceiling-mounted TV screens. The scene outside upstaged the movie in any case, as it has been doing for the last several million years, as the Kaibab Plateau has pushed its dome upward and the Colorado has stayed roughly where it had been since the many millions of years before that, when it wandered lazily across a flat plain.

As ranking canyons go, the Grand Canyon is almost too grand. It’s freaking huge. From the air I find it far more dramatic to peer down into its narrower regions, such as the one above, which is early in the Colorado’s course through the canyon. The series follows the canyon from east to west, from not far below Glen Canyon dam and the Vermillion Cliffs area to Vulcan’s Throne and Lava Falls, where relatively recent flows have slopped their blackness down across the canyon’s iconic layer-cake strata.

What is most amazing to me about this corner of The West is that it was obviously placid through so many time stretches across the last almost two billion years. The West is painted with the colors of long periods of relative quiet, as sands and silts and gravel and cobbles were deposited by braided rivers and transgressing seas.

All of the Grand Canyon’s strata were laid down before the age of dinosaurs. Younger layers such as those comprising the Vermillion Cliffs to the East, the Grand Staircase upstream in the Glenn Canyon area, in Canyonlands, Arches, and most of Utah’s most colorful layer-cake displays — Bryce, Zion, Capitol Reef, Cedar Breaks, San Rafael Reef and Swell — are comprised of younger rock eroded off the top of the Kaibab Plateau.

Some of the shots were taken with my Canon 30d, and others with my tiny PowerShot 850. which does a better job of shooting straight down through the window. Its smaller lens distorts less through the plane’s multiple layers of bad glass and plastic windows. And the display on the back lets me shoot without looking through an eyepiece. It’s not perfect, but not bad, either.

I still miss my Nikon Coolpix 5700, which took lots of great pictures out plane windows, and was frankly much better at that job than the Canon, mostly because the Coolpix’ objective lens was smaller (again, better for looking at angles through the terrible optics of plane windows), and partly because the camera’s flip-out viewer allowed me to hold the camera to the window at angles I could not put my face, but where I could still see and frame the view.
