Crop circles

The first series of photos shows the stunning topography I was observing from the planes on my way to New Mexico. For a Dane who hasn't been around much, it is unreal. The first thing that puzzled me: What's up with all the circular fields? In Denmark, plenty of water falls from the sky. But for the states on the eastern side of the Rocky Mountains this is not the case, so the water required is taken from below instead. An irrigation system rotates around a central drilling, resulting in the circular fields.

A note about the images from planes: Those who have been flying know that you don't have as clear a view of the ground as a lot of the images suggest. 10 km of atmosphere causes a significant haze, but some processing in Photoshop can improve hazy photos dramatically as I was very happy to find out.
