Yosemite

Yosemite

Yosemite was proclaimed a national Park on October 1, 1890. Two men by the names of Galen Clark And senator John Conness were concerned about the effects of local commercial interests. The two decided to advocate for protection. On June 30, 1864 the Yosemite Grant was created.

Yosemite

Sometime about 10 million year’s ago the sierra Nevada desert was brought up and then tilted and formed The Western Slopes and the larger Eastern Slopes. This uplift increased the steepness of the streams around the area. Over time weathering and erosion have been responsible for many landmarks at the park.

YosemiteMost landforms are composed from granitic rock. A few of the landforms are metamorphosed volcanic and sedimentary rocks.

To the right is El Capitan. El Capitan is made up mainly of granite. Erosion is responsible for forming many of the landforms in the park much like this one.

Environmental Issues

Yosemite

Everyday changes are happening in Yosemite’s Habitat. The invasive species are eating away and deteriorating the park. Fires are consuming the wildlife and its habitat. Light Pollution effects the natural life cycle of the animals. Research while meaning well leaves its footprint in the park

Environmental Issues

•External Issues are almost always created by humans or man made resources.

Yosemite

Yosemite also has many external Environmental Issues. They have noise pollution which is very disruptive. The deteriorating climate which is causing multiple issues inside of the park. They also recently had a dam removed which increased the water flow, allowed organisms to swim upstream, and changing erosion patterns.

Yosemite

Technology is very important in the ongoing process of trying to keep the park safe and protected. Video Cameras can be used to monitor conditions in the park from remote locations. Satellites provide weather information and trends that can be used in preserving the park.

The Half Dome

Half Dome is a granite dome in Yosemite National Park, located in northeastern Mariposa County, California, at the eastern end of Yosemite Valley, possibly Yosemite's most familiar rock formation. The granite crest rises more than 4,737 ft (1,444 m) above the valley floor.

El Capitan

El Capitan is a 3,000-foot (910 m) vertical rock formation in Yosemite National Park, located on the north side of Yosemite Valley, near its western end. The granite monolith is one of the world's favorite challenges for rock climbers.

Dana Meadows

The Dana Meadows can be found at the eastern entrance to Yosemite National Park, at the foot of Mount Dana, not far from Tuolumne Meadows and the Tioga Pass entrance station. The Dana Fork of the Tuolumne River originates adjacent to the meadows, and flows west through them towards its junction with the Lyell Fork of the Tuolumne River.

Mount Gibbs

Mount Gibbs is located in the Sierra Nevada Mountains of the U.S. state of California, 2.6 miles (4 km) south of Mount Dana. The mountain was named after Oliver Gibbs, a professor at Harvard University and friend of Josiah Whitney.  Its peak lies on the boundary between Yosemite National Park and Inyo National Forest.

Pacific Crest Trail

The Pacific Crest Trail (also known as the Pacific Crest National Scenic Trail) is a long-distance mountain hiking and equestrian trail that runs in Washington, Oregon, and California between Mexico and Canada.
