In my career I often flew somewhere in the world once or twice a month. That gave me enough seat time to be able to choose the seat I put my butt in. No guarantees about the quality of the window but I always sat ahead of the wing on the non-sunny side and, sorry but I never pulled my shade down so others could watch their movies. Instead I had my camera pointed out the window, usually with a 300mm lens and an f-stop of 11 or more. Maybe they were not razor sharp but good enough for me. And all, of course, pre-drone! The results often blew my mind. Flying over Lake Erie’s ice is just one example.

Pertinent Technical Details
I made this image on an old Minolta digital camera set at a mere f/5.5 and shot at 1/1000 and ISO100. I had to make surprisingly few adjustments in LR to end up with this image.
WOW! That’s an unusual sawtooth ice pattern. Probably a pressure effect. The only other instances of such pressure solution patterns that I have observed are in limestone/marble.
@Bill_Pelzmann , I suspect you are right that it is a pressure ridge that collapsed but, needless to say, I did not get any closer than 20,000 feet! The diagonal light gray lines are snow drifting. I never get tired of looking at these patterns. Would love to see similar ones in stone if you have them.
John: I use my phone to shoot out of windows and have gotten some interesting views. I would never in a million years suspect what this was. My first irreverent thought was, “Flip this on its side and you have a crazy EKG plot.” Terrific abstract and a thoroughly unique opportunity realized. Most excellent. >=))>
John, in rocks these pressure solution contacts are called “stylolites”.
Here is a link to a Wikipedia photo: https://en.wikipedia.org/wiki/File:Stylolites_mcr1.jpg
Your example is on a vastly larger scale. Of course, ice dissolves much faster than rock.
