Yosemite National Park is a United States National Park spanning eastern portions of Tuolumne, Mariposa and Madera counties in the central eastern portion of the U.S. state of California, commonly referred to as Northern California. The park, which is managed by the National Park Service, covers an area of 747,956 acres (302,687 ha; 3,026.87 km2) and reaches across the western slopes of the Sierra Nevada mountain chain.
Over 3.7 million people visit Yosemite each year most spend the majority of their time in the seven square miles (18 km2) of Yosemite Valley.
The geology of the Yosemite area is characterized by granitic rocks and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and then tilted to form its relatively gentle western slopes and the more dramatic eastern slopes. The uplift increased the steepness of stream and river beds, resulting in formation of deep, narrow canyons.
El Capitán (Spanish for The Captain, The Chief) is a vertical rock formation in Yosemite National Park, located on the north side of Yosemite Valley, near its western end. The granite monolith extends about 3,000 feet (900 m) from base to summit along its tallest face and is one of the world's favorite challenges for rock climbers and BASE jumpers.
Nevada Fall is a 594-foot (181 m) high waterfall on the Merced River in Yosemite National Park, California. It is located below the granite dome, Liberty Cap, at the west end of Little Yosemite Valley. The waterfall is widely recognized by its "bent" shape, in which the water free-falls for roughly the first third of its length to a steep slick-rock slope. This mid-fall impact of the water on the cliff face creates a turbulent, whitewater appearance in the falls and produces a great deal of mist which covers a wide radius, which led to its current name (Nevada is an old Spanish word meaning "snowy").
Half Dome is a granite dome at the eastern end of Yosemite Valley in Yosemite National Park, California. It is possibly Yosemite's most familiar rock formation. The granite crest rises more than 4,737 ft (1,444 m) above the valley floor.
Besides the pictures seen above I took some more pictures as you can see at the following album. The weather was not so good but still the things you can see at Yosemite Park are quite nice to look at it!
And if you ever get the chance to stay at Yosemite try to get one of the rare places at the campgrounds!
