I’m a little late with this post because I just returned from a visit to friends and family in San Francisco. I like a window seat when I fly, and no matter how much reading material I bring, I mostly look out the window. I like to watch the maze of taxiways resolve into a map of the airport, and when it disappears in clouds I hear Joni Mitchell in my head: angel hair, ice cream castles, feather canyons, she said. She didn’t mention this one, a teddy bear, or maybe my cat waiting for me at home. 

Then we’re above the clouds looking down. I watch for mountains carrying snow maps of their canyons and ridges, as natural as the crinkly lines of rivers, or the clouds and their shadows. But what about the big smooth snowfields – treeless due to landslides, or landscaped into ski resorts? The hand of nature or the hand of man? 

There’s no question about it when we come to the green circles of irrigated farms. The first time I saw these they made me laugh – could anything be more incongruous with natural landscapes? It’s blatantly obvious that they’re not natural, but why is that? Nature pulls off perfect form with flowers, and likely with some of the plants being grown in those circles. These are on a grid and straight lines are another tip-off of human activity, but I’ve seen circles randomly placed and they looked just as unnatural as these.

Earth, we’re told, is not a perfect sphere, but a lumpy one. From cruising altitude you can just see the curve in the earth’s horizon, a small version of those photos of earth from the moon. For me it packs the same message: we all live here; we’re all in this together. We share the sky, too. On cross country flights it’s not unusual to pass a plane going the other way, whose progress in the opposite direction gives the illusion that it’s zipping along much faster than we are. Then I think of a woman in that plane looking out her window and seeing our plane zipping past hers. Maybe she’s taking a photo of us.

Some four and a half hours after we lifted into the sky, we came back down again. One last view of Detroit area street grids, and the big picture so clear from our high perspective fragmented back into the tangle of details we live in. I’ll be knee deep in them tomorrow, but right now I’m going to fix a cup of tea, sit here, and think about the sky.
