The Act elevated sections of the park to a "highly protected" status to prevent the development of these areas and allow nature to flourish. These highly protected sections compose 89 percent of the park.

Two wilderness areas, named for Ansel Adams and John Muir, respectively, are also protected by this act. Despite the vast areas that are protected, visitors still flock to the Park. Yosemite is known for spectacular views but is also teeming with wildlife. Grizzly and Black bears are common throughout the park but many animals were hunted and trapped during the early days of the park to near extinction. The Park Service has worked hard in recent years to reintroduce and reestablish many species back into the park.

Some of these species include Bighorn Sheep, Peregrine falcons, and great gray owls. In the next few years, Yosemite National Park will celebrate several impressive milestones. June will be the th anniversary of the original Yosemite Act which began to process of creating the National Park. Another important anniversary is the th year of the under-appreciated National Park Service to be celebrated in August of Yosemite National Park has a rich and varied history and is an essential piece of the American landscape.

It is a cherished landmark preserved for the present generations and for future generations to come. It is worthwhile to take a moment, when gazing upon the bounty of Yosemite, and thank the men who fought so hard to keep the valley in all her elemental glory and allowing regular citizens the opportunity to bask in the marvel of nature.

Yosemite National Park reflects the passage of time and represents the promise of the future within its panoramic views of ageless earth and sky.

Yosemite weather is wonderful and one of the reasons folks enjoy visiting this park so much. Here you will find facts on they type of weather conditions you can expect when visiting Yosemite and what to pack!

Yosemite Facts: Yosemite Valley is visited by more than million people and there is a reason so many folks come here.

Yosemite National Park lies within the Sierra Nevada Mountains, an asymmetric mountain range in central California near the eastern border of the state.

The mountains, valleys, granite cliffs, waterfalls, and glaciers of Yosemite have inspired people for generations, including photographer Ansel Adams, naturalist John Muir, and countless hikers and rock climbers. The landscape of Yosemite National Park has changed dramatically in the past million years.

Uplift, erosion, and glaciation have shaped the unique scenery of Yosemite National Park. A view of Mt. Dole, Credit: Richard B. Dole, USGS. Public domain. The oldest rocks in Yosemite formed from sediments and submarine volcanic material.

The sediments originated from continental sources and were deposited in shallow water near the continent creating limestones, sandstones, and shales. A convergent plate boundary where two tectonic plates collide later transported these sediments and igneous rocks eastward.

However, some outcrops of metamorphic rocks Shoo Fly Complex and the Calaveras Complex that did not erode away can still be found today on the western side of the park. Yosemite is known for its granitic rock formations, a type of intrusive igneous rock that forms as molten rock slowly cools deep underground. The ancestral North American continent was moving northwest toward its present location about million years ago. Subduction, a process where tectonic plates collide and the denser plate is forced downward beneath the less dense plate, initiated about million years ago.

In this case the Farallon Plate oceanic crust descended below the North American Plate continental crust , causing chemical and physical changes in both tectonic plates and partial melting of the Farallon Plate.
