While Tuesday was brilliantly sunny, most of yesterday was hazy and covered in wispy cloud. Not the kind of light you're looking for on a day trip to Canyonlands National Park. So, to paraphrase an old saying, when life gives you lemons, open Photoshop. Try B&W, bump up the saturation and contrast, leave it dark, sharpen like crazy.
And by the way, I was wrong when I said yesterday that there are only two national parks with arches. The second photo is Mesa Arch in Canyonlands. A commenter told me that Bryce Canyon, to the west in Utah, has some, too.
