According to geologists, Bryce Canyon presents a landscape of at most 100 million years old. The geological processes that gave it its present forms has been going on for all these years. The area in which Bryce Canyon is located was alternatively sea, coast, the bottom of a great lake and after that again coast. All these phases gave Bryce Canyon its present-day appearance.
The ever-changing water masses in particular caused the constant smoothening and chiselling of the area. At one stage great lakes emerged and the level of the water surface changed.
And at another wide and fierce rivers flowed here.
These water masses often changed in terms of shape and size.
This was mainly the result of changes in climate and rainfall.
The rivers carried stony materials down from the mountains and deposited it at other places. And sometimes the water disappeared altogether.
One of the first residents of this area was the raven. It is not beyond him to attract attention or, more to the point, beg for a biscuit.
As in the other National Parks in the United States, feeding the animals is absolutely prohibited. If the animals get used to being fed, they will relate people to food. Wilderness should be real wilderness.
These are pronghorns together with their young. They are America's fastest land mammals. They can reach speeds up to 100 kilometres an hour, and they can jump more than 6 metres.
