A rainbow through an Elephant Rock Arch at Valley of Fire State Park in Nevada.
This is only the 2nd time I've shot a rainbow through an arch. Earlier that day I was out hiking in the rain at Valley of Fire. I just kept shooting for hours and caught a few rainbows. Not lucky, it's just saying hey it's raining so I should be waiting for it! It is lucky that it happened the first time I attempted to shoot this arch.
