Jewel Rock, Red Mountain

"Jewel Rock", upheld by pinnacles in the amphitheater at Red Mountain

Erosion is the process wherein beautiful things are created as they fall apart.

The amphitheater at Red Mountain on the Coconino National Forest northwest of Flagstaff, Arizona is a perfect example. 

Red Mountain is a 1,000 foot tall cinder cone volcano created from a fiery crack in the earth about a million years ago. Some time later, its northeast flank blew out in another explosion, and its exposed innards have eroded into weird and wonderful pinnacles called "hoodoos".

In this photo, a harder boulder came to rest upon relatively softer material, which seem to be holding it up to the sky. It's like a diamond in its setting on a ring.
