Bryce Canyon National Park in southern Utah is home to the greatest collection of distinctive spire-shaped rock formations called hoodoos on Earth. Its super-ancient sediment layering dates back to the end of the Cretaceous period, more than 66 million years ago.

The fairy tern is a similar size to a hooded plover - so tiny, it would sit comfortably in the palm of your hand. They lay just two eggs, onto the beach sand. See these remarkable images from Tasmanian-based bird ecologist Dr Eric Woehler.
