High Desert Majesty: Temple of the Sun and Temple of the Moon, Capitol Reef National Park, Utah, USA. My wife and I went road tripping through Capitol Reef last year for spring break. The new spring green had just set in and contrasted so nicely with the red rock and the blue sky. It was so rich and vivid already, it took very little coaxing in post to make it pop.
My wife liked it so much, she asked for a large print of it for her birthday, to hang in our living room. And my younger son has already claimed the print after my wife and I are gone.
