Here's an explanation [link] of this stunning formation. It is called Anti-Crepuscular Rays.
I've only ever seen a pink band across the horizon at twilight, but this afternoon's display blew my breath away. The unusual formation in the sky, really captivating me as I took this photo. It felt like a scene from some kind of alien movie, as the creatures from another world land on Earth.
love the clarity and detail you got in the rocks. thats not as easy as people think. i know I struggle with that sometimes. of course I shoot into the sun too much, but anyway, great job. love this shot.
