Mount Lyell (California)

Mount Lyell (California)

Mount Lyell is the highest point in Yosemite National Park. It reaches up to 13,114 feet (3,997 meters). It is at the southeast end of the Cathedral Range, about 1 and a quarter miles (2 kilometers) northwest of Rodgers Peak. This tall mountain, along with nearby Lyell Canyon, was named for Charles Lyell, a famous geologist from the 1800s.

One interesting feature of Mount Lyell was one of the last glaciers in Yosemite, called the Lyell Glacier. Today, it is more like a permanent ice field than an active glacier. Mount Lyell helps shape the land. It separates the Tuolumne River watershed to the north, the Merced River to the west, and the Rush Creek drainage to the southeast.

Climbing

The most common way to reach Mount Lyell starts from Tuolumne Meadows along the John Muir Trail. This hike is about 25 miles long and goes up about 4,500 feet. It is easy at first but becomes harder near Donohue Pass.

Most people go over or around the Lyell Glacier to reach the top. Because the glacier changes with the seasons, it’s best to check conditions before choosing a path. One route goes along the northwest Ridge, between Mount Lyell and Mount Maclure. The rocks near the top can be unsafe when there is less snow, so climbers need to be careful. There are other paths on the south and west sides, but they are longer and more difficult.

Climate

Mount Lyell has special weather because it is very tall. The temperature there changes a lot, and it often snows. This keeps the area around Mount Lyell cool and snowy for much of the year.
