The Milky Way over Monument Valley.

You don't have to be at Monument Valley to see the Milky Way arc across the sky like this -- but it helps. Only at Monument Valley USA would you see a picturesque foreground that includes these iconic rock peaks called buttes . Buttes are composed of hard rock left behind after water has eroded away the surrounding soft rock. In the featured image taken a month ago, the closest butte on the left and the butte to its right are known as the Mittens , while Merrick Butte can be seen farther to the right. Green airglow fans up from the horizon. High overhead stretches a band of diffuse light that is the central disk of our spiral Milky Way Galaxy . The band of the Milky Way can be spotted by almost anyone on almost any clear night when far enough from a city and surrounding bright lights , but a sensitive digital camera is needed to capture these colors in a dark night sky.
