LOL! It's irrigation. They put an irrigation pipe on a pivot with a big wheel on the other end, and it runs around in a circle, watering the field. No water, no green stuff. Makes circular fields. Rectangular fields have a different system, where the irrigation pipe runs across the field on big tires in a straight line. I could spin you a yarn about aliens if you wanted me to, but really - it's just the farmers. Great shot! :)

Area 51!!! Your lucky they did not shot you down, LOL!!! No, No, LOL!!! Cool Pick though!!!

wow marilyn this is really a cool shot ,so detailed from way up there .looks a bit like a giant crossword puzzle :o)..excellent capture mick

And this is proof that the world is round. Nice capture. Aloha

Fantastic capture.

excellent capture, its always great getting a birdseye view especially things you normally wouldn't catch on the ground such as this, great work !!

I noticed something like this in one of Richards uploads a few weeks back and wondered what they were myself. I even went on Google Earth to see if I could find them but no luck. A very interesting shot Marilyn, I have yet to gain my wings having never flown anywhere. Superb capture. Bravo!!!!!

The real explanation is not half so interesting as those from our fertle imaginations. Still, I suppose 'fertile' is a good choice of words in the circumstances ... Mike

so, do the farmers plow in circles? we think not! it aliens for sure!

Mmm! Not sure I believe any of you! Very interesting pic, anyhow! Maybe its a giant sort of bingo game.

I love this picture and the crop-circles are awesome; yeah, they are irrigation artifacts (I've seen a couple in Illinois of all places) but they DO look like either a giant crossword puzzle or something else a bit stranger! I love the capture of textures here as well as the sense of tawny color. Yeah, you were up there for sure! The earth's curvature is an awesome compliment to everything else in this picture.

I don't get to myself very often but I LOVE flying and looking at all the beautiful and puzzling things you can see from that perspective. I am always glued to the window if at all possible. This is a wonderful image.

fun shot. lots to see. I see you got my seat on that plane - always right by the wing so I can listen to the engine all the way! :-)

Keep looking by the window ! I'm still amazed to see people reading newspapers in a plane without even take a look !

WOW I love this, did you photoshop this or is it for real??

Crop circles...hmmm...perhaps missile silos? Keep this photo away from the Feds...lol Great capture, Marilyn, especially the surface, below and the awsome curvature of our planet.

Hi Marilyn Kay this is a joy to view so many smiles I see awesome capture sweet weekend to you warm hug, Linda Kaye :-)

Fantastic photo Marilyn!!! one of your best ever :-) and yep I sure see the curvature! have a great day :-)

big hugh UFO,s landed here lol cool image.

Don't nobody make no fun of crop circles, ya heah!!!! Interesting capture taken through the window of your spacecraft, showing the ubiquitous circles and the curvature of the earth, Marilyn! My brother, who lives in Santa Fe, NM, might know something more about this irrigation phenomena.

Wonderful photography. Superbly wrok!! Congratulations!! A million stars ****Happy Weekend. Luminous blesing.Ludy (Sorry to have that to write the same thing in English to all, but are few the words that I have in English to say)

I saw something like that before when i'm "traveling" in google earth around the states. I always asked me what it could be. So thanks to auntietk. Now o know. Thanks to you marilyn for sharing the Picture. Every day learning some thing new!
