Considered like one of the natural wonders of the world is situated inside the Natural Park of the Big Cannon, U.S..
The Big Cañon (the Grand Canyon) is a showy and escarpada throat excavated by the river Dyed in the north of Arizona, United States. The Cannon is considered like one of the natural wonders of the world and is situated in his main part inside the National Park of the Big Cannon (one of the first Natural Parks of the United States). The president Theodore Roosevelt was the main promoter of the area of the Big Cannon, visiting it in numerous occasions to hunt cougars or to enjoy of the impressive landscape.
The cannon was created by the river Dyed, whose course undermined the terrain during million years. It has some 446 km of length, has mountain ranges of between 6 to 29 km of width and achieves depths of more than 1.600 m. Near of 2.000 million years of the history of the Earth have remained exposed while the river Dyed and his tributarios or tributaries cut layer after layer of sediment at the same time that the plateau of the Colorado elevated .
Apart from the occasional tourist visit to the embroider south with his 2.134 metres on the level of the sea, the rafting or descent of rivers and the walking are activities especially popular. The bottom of the valley is accessible walking, in mule or in boat descending from the top of the river. The civil servants of the park do not advise to realise in an alone day the excursion to descend to the course of the river and go back to go up because of the distance, the effort required and the danger of heat exhaustion by the high temperatures that achieve deep down. Even the excursions by the edge have to do with care in some points; with frequency there are signals of danger along the tracks that visit the edges of the cannon.
They exist companies that organise descents in rafting of the river, generally in boats for 15 people instrumented with engine fueraborda, are used to to split of Lee’s Ferry and arrive until Diamond Creek lasting the trip some 6 days. The boats instrumented only with oars are used to to take some 2 weeks in completing the trip. Also they exist companies that organise excursions for tourists in helicopter to the Big Cannon.
