It has jagged ridges on its sides. Very few plants grow near the top. One small plant is called a sky pilot. It grows low to the ground. Some birds and butterflies visit the mountain too.

It is the highest point in the lower part of the United States. The peak is 14,505 feet high.

The mountain is made of granite. This is a very hard rock. Long ago, hot melted rock rose under the ground. It cooled and became granite. Later, the earth pushed the mountain up. Rivers and ice helped shape its jagged edges.

The top of the mountain is very cold. This is called an alpine climate. Very few plants live there. One small plant is the sky pilot. It grows low to the ground. You might also see a gray-crowned rosy finch. This is a small bird.

Many people hike to the top. Most use the Mount Whitney Trail. You must get a permit to hike there. This helps protect the mountain. On the summit, there is a stone hut. It is called the Smithsonian Institution Shelter.

Mount Whitney is a famous mountain in California. It sits in the Sierra Nevada mountain range. This peak is the highest point in the contiguous United States. It reaches an elevation of 14,505 feet.

The mountain is located on the border of Inyo and Tulare counties. It rises very high above the Owens Valley to the east. On the west side, the mountain is part of Sequoia National Park. The summit is also the end of the John Muir Trail.

The mountain is made of very hard granite rock. Long ago, hot molten rock rose under the ground. This rock cooled and became part of the Sierra Nevada Batholith. The Earth's crust is slowly being stretched in this area. This stretching causes the mountain to rise up on the east side.

A fault system helps push the mountain higher. Over millions of years, rivers and glaciers wore away softer rocks. This left the tough granite of Mount Whitney behind. This process created its jagged ridges and dome shape.

People have been exploring this peak for a long time. In 1864, scientists named it after Josiah Whitney. He was the state geologist of California. Some people called it Fisherman's Peak. This was the name used by three men who first reached the summit in 1873.

The Paiute people had their own name for it. They called it Tumanguya, which means "the very old man." They believed a Great Spirit once lived in the mountain. In 1904, a new trail was finished to help people climb it.

The weather at the top is very cold. This is called an alpine tundra climate.

Summer temperatures can change very quickly. They can go from below freezing to very hot. Very few living things can survive near the summit. One plant is the sky pilot. It is a cushion plant that grows low to the ground. You might also see a gray-crowned rosy finch bird.

Many hikers visit the mountain today using the Mount Whitney Trail.

This trail starts at Whitney Portal. The hike is about 22 miles round trip. You must get a permit from the Forest Service to hike there. This helps keep the mountain safe from too many people. On the summit, you can find the Smithsonian Institution Shelter.

Mount Whitney is a massive granite peak located in the Sierra Nevada mountain range of California. It holds the title of the highest point in the contiguous United States. The summit reaches an elevation of 14,505 feet.

This mountain sits on the boundary between Inyo and Tulare counties. Geographically, it is a striking landmark. It rises sharply above the Owens Valley to the east. On its western side, the mountain is part of Sequoia National Park. The summit also serves as the southern terminus for the John Muir Trail.

The mountain was formed through complex geological processes. During the Cretaceous period, masses of molten rock rose beneath the surface. This material solidified underground to form large expanses of granite. This granite is part of the Sierra Nevada Batholith. Over the last 2 to 10 million years, the Sierra Nevada was pushed upward. This movement was caused by a fault system running along the eastern base.

As the mountain rose, glacial and river erosion stripped away softer rock layers. This left behind the resistant granite that makes up the peak today. The eastern slope is much steeper than the western slope. This is because the Sierra Nevada is a fault block that is anchored to the west and rising on the east. This rising occurs because the Earth's crust is being slowly stretched in this region.

Because of its high elevation, Mount Whitney has an alpine tundra climate. This means the weather is very harsh and changes quickly. Summer temperatures are highly variable. They can drop below freezing or reach high temperatures during extreme heat waves in the Owens Valley.

The mountain is also a major point for hydrology, or the study of water. It sits on the Great Basin Divide. Water on the western side flows into Whitney Creek and then into the Kern River. This river eventually reaches the Tulare Basin. On the eastern side, water flows into Lone Pine Creek. Much of this water is diverted through a sluice into the Los Angeles Aqueduct. Some water continues to the Owens River and ends at Owens Lake.

The history of exploring Mount Whitney is full of interesting stories. In July 1864, the California Geological Survey named the peak after Josiah Whitney. He was the state geologist of California. Before it was officially named, three men from Lone Pine reached the summit in 1873. They were on a fishing trip and called it Fisherman's Peak.

The indigenous Paiute people had their own name for the mountain. They called it Tumanguya, or Too-man-i-goo-yah. In their language, this means "the very old man." They believed a Great Spirit once lived in the mountain. Later, in 1881, Samuel Pierpont Langley used the summit to observe solar heat.

Life near the summit is difficult due to the extreme conditions. Very few plants can survive in this environment. One example is the sky pilot. This is a cushion plant that grows very low to the ground to stay protected.

The only animals found near the top are transient visitors. These include the butterfly Parnassius phoebus and the gray-crowned rosy finch. These species move through the area rather than living there permanently.

Today, many people visit the mountain via the Mount Whitney Trail. This trail begins at Whitney Portal, which is at an elevation of 8,360 feet.

The hike is approximately 22 miles round trip. It involves an elevation gain of over 6,100 feet. To prevent overuse, the Forest Service requires permits. Hikers must apply through a lottery system held between February and March. Some people attempt to hike the entire route in a single day. This requires starting before sunrise and hiking for 12 to 18 hours.

Safety and shelter are important on such a high peak. In 1904, the first trail to the summit was completed by Gustave Marsh. Sadly, just four days later, a hiker named Byrd Surby was killed by lightning on the summit. In response, Marsh built a stone hut.

This structure became known as the Smithsonian Institution Shelter and was completed in 1909. The mountain also offers technical challenges for climbers. The East Face is a famous route that involves technical free climbing. Other areas, known as the "needles," offer world-class big-wall climbing opportunities.
