I got one picture that I really like. It's a pseudo-HDRI, but that isn't what makes it look like it does. After a rain shower, teddy bear cholla seems to glow. I don't know if it's from sunshine on them with dark clouds around them, or because the rain has washed dust off the spines, or what it is. I was walking along the trail and this cholla grabbed my attention (instead of my skin). For once, I think the picture gives an idea of what it really looked like.
I wasn't out there long enough to catch any great cloud pictures, though I got a couple I like. Click below to see all of the pictures.
