Split Mountain is a striking geological feature located in the Eastern Sierra Nevada Mountains of California. Known for its unique, jagged peaks and dramatic rock formations, Split Mountain rises to an elevation of 14,058 feet (4,286 meters), making it one of the tallest peaks in the Inyo National Forest and the California Sierra range. The mountain gets its name from a distinctive crack that splits the summit, giving it its iconic “split” appearance. Split Mountain is a popular destination for climbers, hikers, and outdoor enthusiasts seeking an adventurous experience in the heart of California’s rugged wilderness.
Reaching Split Mountain requires a combination of driving and hiking, as it is located in a remote part of the Inyo National Forest. Here's how you can reach the base of Split Mountain:
Due to the difficulty of the hike and the remote location, it is important to check trail conditions and be prepared for altitude changes and variable weather.
The weather at Split Mountain can be unpredictable, especially as you ascend in elevation. Due to its location in the Sierra Nevada, the area experiences a high-altitude climate with cold temperatures in the winter and moderate temperatures in the summer. Summer temperatures at the base of the mountain range from 60°F to 80°F (16°C to 27°C), while temperatures at the summit can drop below freezing, even in the summer.
Winter (November to March) brings cold weather and heavy snow, making the mountain difficult to access during this time. For hiking and climbing, the best months are from late spring to early fall (May to October). The early summer months are the most popular for climbers, as the snow has usually melted, providing easier access to the mountain's trails.
The ideal time to visit Split Mountain is between May and October, when the weather is more favorable for hiking and climbing. Early summer (June to July) is the most popular time to climb, as the snow is usually gone, and the weather is stable. However, it can get quite hot at the base of the mountain during the summer months, so it’s important to start early in the morning to avoid the heat of midday.
Fall (September to October) is also a great time to visit, as the temperatures are cooler, and the surrounding landscape is painted with fall colors. Winter (November through March) is not ideal for climbing due to snow and icy conditions, making it necessary to check trail conditions before attempting the ascent.
Split Mountain is famous for its stunning geology and challenging climbing routes. The mountain’s distinctive “split” summit, which is a result of tectonic forces, makes it an iconic landmark in the Sierra Nevada. The mountain attracts outdoor enthusiasts from around the world due to its difficult and rewarding climbing opportunities, stunning vistas, and proximity to other beautiful natural sites like the Inyo National Forest and the nearby White Mountains.
In addition to its popularity among climbers and hikers, Split Mountain is also well-known for being a part of the John Muir Wilderness area, a protected region named after the famous naturalist and conservationist. The area around Split Mountain is rich in biodiversity, providing wildlife enthusiasts with opportunities to spot various species of birds, mammals, and plants.
Split Mountain is located within the Inyo National Forest, and access to the mountain requires a permit for hiking and climbing. The Paiute Pass Trail is the primary route to the summit of Split Mountain, and hikers will need to secure a wilderness permit for overnight trips. Permits are issued by the Inyo National Forest and can be obtained at the Eastern Sierra Visitor Center in Lone Pine or online through the National Park Service website.
There are no fees for general access to the area, but the wilderness permit is required for camping and climbing. Keep in mind that the area around Split Mountain is remote, so visitors should come prepared with enough food, water, and gear for the trip. There are no facilities at the trailhead or along the trail, so visitors must bring all necessary supplies.
Split Mountain, like many of the peaks in the Sierra Nevada, was formed by millions of years of geological activity. The mountain’s iconic split appearance is a result of tectonic forces that created the jagged ridges and valleys of the region. Split Mountain is part of the larger Inyo Mountains, which are known for their rugged terrain and stunning vistas.
The region has a rich history that includes Native American tribes such as the Paiute and Shoshone, who lived in the area for thousands of years. The mountain is named after the Paiute tribe, who considered the area sacred. European settlers began exploring and mapping the Sierra Nevada in the mid-1800s, and the mountain became known to climbers in the early 20th century.
While Split Mountain itself does not feature any human-made architecture, the surrounding wilderness and national forest are home to rustic campsites, old mining structures, and historical landmarks that provide insight into the region's history.
