Yosemite

Introduction
Yosemite National Park is without a doubt, one of America’s most beautiful and well-known parks. Due to the diversity of attractions the park offers, including high Sierra Peaks, the highest highway pass in California called the Tioga Pass, the Yosemite Valley, the Merced River, acres of high altitude backcountry, waterfalls, and some of the largest living things on earth in the sequoia groves tourists from all over the world visit. The most famous section in the park is Yosemite Valley, where El Capitan, Half Dome, Yosemite Falls, and other places to explore nature’s beauty lie. Yosemite Geography

Yosemite National Park is located in the Central of the Sierra Nevada Mountain Range in California. The park is 1,189 square miles, comparable to the size of the United State’s state of Rhode Island. Lakes, ponds, streams, hiking trails, and roads are some of the many features that attract tourists. Nearly all the landforms in the Yosemite area are cut from a mass of intrusive igneous rock that formed below the surface of the earth. Some of the park’s landforms are metamorphosed volcanic and sedimentary rocks. Erosion that acted upon different types of uplift is responsible for creating the valleys, canyons, domes and other features found in this national park.

Some of the popular features Yosemite possess’ are Yosemite Valley—where the majority of visitors stay, the Tunnel View—which is the first view of the valley when visitors enter the park, El Capitan—a major granite cliff that oversees Yosemite Valley, and Sentinel Dome and Half Dome that offer a diverse range of climbing routes. Also found within the park are the breath-taking giant sequoia trees. Perhaps the most remarkable sequoia in the park is the Grizzly Giant, believed to be more than 2,700 years old and the oldest known sequoia tree. Yosemite is known for its high concentration of waterfalls. Hanging valleys in the park offer a place for waterfalls to exist. During the snowmelt season, April, May, and June, waterfalls are able to flourish.

Yosemite has a Mediterranean climate, which means most of the precipitation falls during the mild winter and the other seasons are considerably dry. Snow doesn’t stay on the ground until November, and then accumulates until March, when it begins to melt. There is a large temperature range due to elevation diversity and global warming. History of Yosemite

The Yosemite National Park is located in Sierra Nevada in the east-central part of California. The Park is widely spread area of 750,000 acre, with streams that are 1,600 miles long, hiking trails that are 800 miles and the roads that extend up to 350 miles. Yosemite Fall is the highest waterfall in North America, it is considered as the third of the highest waterfall on planet Earth. Another important factor of Yosemite Park would be the numerous of species it contains. Over 300 species of animals can be found in the park. Yosemite is known for its spectacular attractions such as high Sierra Peaks, the highest highway pass in California, the Yosemite Valley, Merced River, and many acres of high altitude backcountry, some of the highest waterfall in the world. Plants are also really high at the Park. Some reaching altitudes from 2,000 feet to the peak of Mr. Lyell. 94.5% of the park’s 747,956 acres is officially classified as wilderness. Moreover, that is one of the main reasons why the park is now protected by the state. One of the very first people to live in Yosemite would be the Paiute and the Sierra Miwok people. They were in the area for a long time before the first white explorations were done in the region. This people were a band of Native Americans called the Ahwahneechee. During the mid 19th century, The California Gold Rush radically increased travel in the area. While the major Jim Savage of the United States Army led the Mariposa Battalion into the west end of Yosemite Park, Chief Tenaya gathered...
