Royal Gorge the Grand Canyon of the Arkansas River 1,250 feet (380 m) in places.
|Royal Gorge Bridge tallest bridge in the world until 2001 when the Liuguanghe Bridge in China was built and topped it.|
Uncompahgre Peak, northeast face, San Juan Range, Colorado, 275 m (550 m rise above surrounding plateau).
Shiprock, New Mexico, United States, 400 m. This photograph was taken from Mesa Verde National Park approximately 80 miles away. It looked like the Disney Cinderella Castle to me.
Cliffs of Mohr Ireland, 217 m above Atlantic Ocean. I could produce a photograph of a very fogged in Cliffs of Mohr because that is what I saw the day I was there but instead I will offer a link that has a better picture. Even in the fog the area held much mystique.
White Cliffs of Dover 100 m above the Strait of Dover. If you take a ferry across the English Channel, the view just keeps getting more and more spectacular.
