Yosemite National Park is a massive protected area in California, USA.

It sits within the Sierra Nevada mountain range. The park covers 1,187 square miles across four different counties. These include Tuolumne, Mariposa, Mono, and Madera. It is bordered by the Sierra National Forest and the Stanislaus National Forest. The park is a designated World Heritage Site. It is famous for its granite cliffs, waterfalls, and giant sequoia groves.

Almost 95 percent of the park is classified as wilderness. This makes it one of the largest habitat blocks in the region.

The landscape was shaped by powerful geological forces over millions of years. About 10 million years ago, the Sierra Nevada underwent uplift. The mountains rose and tilted to create unique slopes. This tilting increased the steepness of river beds. It also helped form deep, narrow canyons. About one million years ago, glaciers formed at high elevations. These massive sheets of ice moved downslope. They carved and sculpted the land into the U-shaped Yosemite Valley seen today.

Human history in the region began long before modern records. The Ahwahneechee people lived within the park for nearly 4,000 years. They called their home Ahwahnee, which means "big mouth."

They were part of the larger Southern Sierra Miwok group. They relied on resources like acorns, salmon, and deer. However, the California Gold Rush changed everything for them. Between 1848 and 1855, over 90,000 European Americans arrived in the area. This caused intense competition for resources. The native population dropped from 300,000 to only 50,000 in just a few decades. This decline was caused by disease, starvation, and conflict.

Conflict eventually led to the Mariposa War in the early 1850s. This was part of the larger California genocide. In 1851, the Mariposa Battalion was formed to drive Native people from the territory. Led by James D. Savage, the group pursued the Ahwahneechee. Chief Tenaya led many of the people during this difficult time. The battalion captured many individuals and moved them to reservations. Some people, including Tenaya, eventually fled across the Sierra Nevada. They settled with the Mono Lake Paiutes. The term "Yosemite" actually comes from the Miwok word for the Ahwahneechee.

It does not mean "grizzly bear," despite a common misconception.

The struggle to protect the land led to the modern national park concept. Early citizens like Galen Clark lobbied to stop commercial development. This effort resulted in the Yosemite Grant of 1864. President Abraham Lincoln signed this grant to preserve the land for public use. This was a historic first for the United States government. Later, in 1890, environmentalist John Muir led a movement to establish a National Park. This movement helped create the entire National Park System.

Today, the park is managed by the National Park Service.

Tourism has grown significantly since the first visitors arrived in 1855. Early travelers like James Mason Hutchings helped publicize the valley. As people visited, businesses like hotels and bakeries began to appear. One famous attraction was the Wawona Tree, or Tunnel Tree.

It was a giant sequoia with a tunnel cut through it for carriages. Sadly, the tree fell in 1969 after a heavy snow. Modern tourism is massive, with about four million visitors arriving annually. In 2016, the park set a record with over five million visitors.

Most people stay within the seven square miles of the valley.

Yosemite remains a vital place for biological diversity and scientific study. It hosts many different species in a protected environment. You can find animals like the mule deer on the valley floor.

The park's ecosystem includes everything from high mountains to lush meadows. It connects many different biological systems within the Sierra Nevada. This makes it a crucial area for nature to thrive.
