Western landforms, California to Nevada and a bit further. The color is completely wonky on this one; I can't really make any sense of it. The big circles, of course, are rotating irrigation systems. I haven't made any top-to-bottom (far-to-near) contrast or color corrections; see how much difference there is? That blue haze adds up. It's also weird how frequently I see a few isolated fields like this, with nothing else for miles and miles.
