The name "Yosemite" comes from the Miwok word for the Indians that lived in the Yosemite Valley - the yo'hem-iteh. (Another source says it's Indian for Grizzly - let me double-check.)
Yosemite includes nearly 1,200 square miles of the western Sierra Nevada. There are 840 miles of hiking trails in the park. The most famous areas include Yosemite Valley, Tuolomne Meadows and Wawona. Famous goals for the tourists include Glacier Point, Half Dome, El Capitan, Yosemite Falls, Bridalveil Fall and Mariposa Grove.
The land was set aside in 1864 and the park was created in 1890, mostly thanks to John Muir who fought for it for many years.
Some of the world's highest waterfalls and the world's biggest trees can be found in the Yosemite. There are over 80 different species of mammals and 250 species of birds.
Ansel Adams has taken hundreds and hundreds of famous photographs from the Yosemite Valley.
The park has 196 miles of roads and 4.1 million visitors every year. The huge impact of all this on the unique environment in the Yosemite, has led to changes in the last years. Car accessibility will be decreased in the close future.
