Archaeology handicrafts and science and technology sites to visit Côte Ouest Etats-Unis

It's a steep slope and can be reached on foot, by bicycle or by shuttle bus (21 stops in the valley, free of charge). It is 13 km long and 1.6 km wide, and is 1,209 meters high. From the bottom of the valley, you can see the steep walls, and the two rocks so often photographed for their beauty: El Capitan and the Cathedral. From the top of the walls fall countless impressive waterfalls, some of which are over 700 meters high. Many hikes start from the surroundings of the valley. The valley is very crowded in summer.

The Grand Canyon of the Yellowstone River extends over 38 kilometers, between the falls, upper and the mouth of the Lamar River. It reaches a depth of 60 to 245 meters and a width of 300 to 1,400 meters. In the upper part, where the throat is deepest and narrower, rocky walls offer beautiful tones ranging from yellow to orange and red brown.

Fine rock needles from erosion flow, isolated, depths, and sometimes a white vapor escapes from hot springs and geysers located at the bottom of the canyon. At the bottom, the Yellowstone River appears to be quiet. In fact, it mutates into rapids which, twice, rush into the depths of huge waterfalls: to the south, at the beginning of the canyon, the Upper Falls (33 meters high), and about 900 meters downstream the Lower Falls or Great Falls (94 meters high).

South of Canyon Village, Hayden Valley is the bed of an old lake formed in the ice age. Its fatty herb and some swampy points attract abundant wildlife (bears, bison, elk) and birds (swans, herons, Canada geese).
It is one of the best places in the park to observe wildlife, including the grizzly bear that, in the spring and early summer, is looking for bison and elk babies. Large bison herds can be admired from spring to early fall. Coyotes notice in the valley. Birds abound along the river. There are many in the Alum Creek vases. America's white ducks, geese and pelicans swim on the river. You can also follow the flight of the white-headed eagle and the northern harrier falcon.

Artist Point offers an impressive view of the Upper waterfalls and Lower Falls. Panoramic path along the edge of the canyon directly. Of Canyon Village, Canyon Rim Scenic Road wins the north wall of Grand Canyon with several beautiful viewpoints including Lookout Point, from where a path to the foot of the canyon, and by a junction, Inspiration Point, from where you have a splendid view of the latter.
