"Sleeping dragon eye" at White pockets, Vermillion Cliffs National Monument, Arizona, United States.

Battleship Wisconsin lets loose with a salvo of her massive Mark 7 16-inch guns.
You can see one of the shells just in front of gas ring as it exits the barrel.
The Nimitz class aircraft carrier USS Harry S. Truman (CVN-75) making her way down the Elizabeth River after departing the Norfolk Naval Shipyard.
For a ship the size of a supercarrier, navigating the river is no small feat. A cloud of silt can be seen behind the carrier, stirred up by her massive screws. Tugs maintain close formation around the carrier, ready to step in if needed.
After navigating the river, the carrier will return to her base at Naval Station Norfolk at Hampton Roads.
At the top of the photo, the stern and upperworks of the Iowa class battleship USS Wisconsin (BB-64) can be seen.
