I have also seen this secret spot referred to as Windstone Arch. Whatever it is called, it is cool!
I’m always surprised at just how rich a glow is created when you have sun reflecting off red rock, onto more red rock. I actually had to desaturate this a bit, although my camera does seem to run a bit hot with reds. There is an endless number of areas worth exploring at Valley of Fire- numerous caves, arches, colorful sandstone, I’m surprised, but glad this area isn’t more popular.
