Here's an image I pulled from the Nature Conservancy's website. This a landscape taken by Chris England within Zion National Park in Utah. As a kid I've been to been to Zion a couple of times and Utah has been a very dear place to me ever sense.
I wouldn't like this image near as much if the tree weren't in the center pulling the two rock formations together. There are also a lot of intense colors in this image, the burnt orange of the rock and the deep blue of the sky go really well together, probably because they're complementary colors. I'll include a link to some more of Chris England's photos.
