Cool Clouds Pictures

As cool pictures go, these amazing clouds pictures from National Geographic are some of our favorite pictures which also make cool desktop wallpapers.

Most common in September and October—and in morning—the clouds can 

travel across the skies at nearly 20 miles (30 kilometers) an hour.
