Nothing could improve on that, could it? How about a full cloud inversion? It's pretty cold at the base of the canyon, so when warmer air traps the cooler air down there and a bit of moisture is included, clouds form and cover the canyon. The result is something that resembles an ocean of clouds. A full cloud inversion contained in the Grand Canyon.

The clouds come to the tops of the Grand Canyon during a full cloud inversion.

The video above and these photos are spiritual sequels to a video and photo project from earlier this year, "Kaibab Elegy." A meteorite streaks over the Grand Canyon, with the Milky Way in the sky.

In particular, he cited the park's "incredible night skies, staggering environment variety between top (rim level) and bottom (river level) of the park and just how weather patterns create a vastly different experience on the north (often more rain and snow) and south (often quite a dry or rainy when it's snowing north) rim" as reasons why it's his favorite park. "You could have freezing temperatures and snow on the rim and 20 degree warmer weather at river level. I can't think of a park where one is confronted with as wide a variety of elements in a span of a few days," he told MNN in an email. A rainbow lens flare captures a tree on the Grand Canyon.

"In 'Elegy' you see the transition from late summer monsoons to late fall cloud inversions while [in] 'Requiem' you see the late fall transition to mid-winter. It's hard not to be inspired at Grand Canyon, or to take a bad shot." Clouds create a shadowy effect over the Grand Canyon.
