The Grand Canyon with star trails captured in a time-lapse photo.

The Grand Canyon is seen in an early evening time-lapse photo. The image captures the canyon's layers in bright moonlight while a tripod holds the camera steady while each star rotates above the Earth. The result photograph is a 360 degree arc of star trails in the night sky.

Sedimentary layers in the canyon range in age from approximately 200 million to 2 billion years old, on a geological timescale. Recent research now indicates that the Grand Canyon itself may have been carved by erosion nearly 70 million years ago.

And this was a place that some people wanted to dam and flood!
