Grand Canyon Star Trails

The Grand Canyon, one of Earth's natural wonders, stretches across this early evening skyscape. The digitally stacked sequence reveals the canyon's layers of sedimentary rock in bright moonlight. These exposed layers range from 200 million to 2 billion years old, offering a window into geological history. Recent studies suggest the canyon itself may have been carved by erosion as much as 70 million years ago.
