Antelope Canyon, USA (4/10)

Another striking natural phenomenon can be seen in the United States, Arizona. The Antelope Canyon is an eight-mile-long, narrow, rocky crack located on a gnawed out tableland. This canyon consists of two parts: up and down. The lower canyon is more easily accessible to tourists, as it is much more flattened. The upper part of the canyon is a very narrow slot, surrounded by rocks of almost 40 meters high. In places, this part is so narrow that there fits only a human hand.
