Hidden at the end of a trail, at the end of the road in the Arches national park, Utah. We are the first to arrive in darkness and choose our spot having scouted the location earlier in the week. As the sun rose, the rock began to change colors, but it was not until the sunlight directly hit the rock that it got this glow. We found it necessary to stand almost under the arch so we could get sky to appear inside it. Fifty feet back, and the arch simply blends into the rock around it.
