Karnak Temple is a huge, open air complex and, after the Giza Pyramids, the second most visited historical place in Egypt.

Rising along the border of Nepal and Tibet, Mount Everest stands as the highest point on Earth, reaching over 29,000 feet into the sky.

The bend is also known as the "bendiest bend on the Rhein."

Eden Islet is a small volcanic tuff cone rising from the clear waters off the northwest coast of Santa Cruz Island.
