About

Lassen Volcanic National Park is located in northern California at the southern end of the Cascade Range. Established in 1916, the park covers approximately 166 square miles (430 sq km) and protects one of the most geologically active volcanic landscapes in North America.

The park is centered around Lassen Peak, the largest plug dome volcano in the world and one of the few volcanoes in the Cascade Range to erupt during the twentieth century. Lassen Volcanic is unique because it contains all four major types of volcanoes—shield, composite, cinder cone, and plug dome—within a single protected area.

The park is best known for its active geothermal features and volcanic landscapes. Visitors are drawn to bubbling mud pots, steaming fumaroles, boiling springs, volcanic craters, alpine lakes, and dramatic mountain scenery. Among the park’s most famous attractions is Bumpass Hell, the largest hydrothermal area in the park, featuring steaming vents, boiling pools, and colorful mineral deposits.

Other popular destinations include Cinder Cone, Manzanita Lake, and the summit trail to Lassen Peak. Hiking, camping, fishing, kayaking, snowshoeing, stargazing, and wildlife viewing are among the park’s most popular activities.

Geographically, Lassen Volcanic National Park lies at the intersection of the Cascade Range, Sierra Nevada, Great Basin, and Modoc Plateau regions, creating exceptional geological and ecological diversity. Elevations range from approximately 5,000 feet (1,525 m) to 10,457 feet (3,187 m) at the summit of Lassen Peak.

The landscape consists of volcanic domes, lava flows, crater lakes, mountain forests, meadows, and hydrothermal areas shaped by ongoing volcanic processes. The park receives significant winter snowfall, with deep snowpacks often lingering into summer at higher elevations. Numerous lakes, streams, and wetlands contribute to the park’s scenic beauty and ecological richness.

Wildlife within Lassen Volcanic National Park reflects the diversity of its mountain ecosystems. Mammals include black bears, mule deer, mountain lions, bobcats, coyotes, river otters, martens, and yellow-bellied marmots. Birdlife is abundant, with bald eagles, osprey, peregrine falcons, mountain bluebirds, Clark’s nutcrackers, and numerous migratory songbirds inhabiting the park.

Lakes and streams support trout populations, while amphibians such as the Cascades frog and Pacific tree frog thrive in wetland habitats. The park’s forests of pine, fir, hemlock, and red fir provide habitat for a rich variety of wildlife and plant species.

Lassen Volcanic National Park plays a vital role in preserving one of the most active volcanic regions in the continental United States. The park protects unique geothermal features, volcanic landforms, mountain ecosystems, and important watersheds while providing opportunities for scientific research into volcanology and geothermal processes.

Its conservation significance is often compared to Yellowstone National Park and Crater Lake National Park because of its volcanic origins, geothermal features, and scenic mountain landscapes. Through its steaming hydrothermal areas, volcanic peaks, alpine lakes, and diverse wildlife, Lassen Volcanic National Park stands as one of America’s most fascinating protected areas and a remarkable showcase of the powerful geological forces that continue to shape the Earth.

Things to See

Apart from Mount St. Helens, Mount Lassen is the most recent volcanic eruption occurring back in 1914.  It was established as a protected area giving researchers an opportunity to study the effects of a volcano.

The surrounding area of Lassen Volcanic national park represents the effects following this volcanic eruption and is now used to evaluate what is next for the Mount St. Helens area.  This is an opportunity to make scientific observations as the area seeks to return to new life and growth.

Mount Lassen

Mount Lassen is also known as Lassen Peak.  It is the southernmost active volcano found amongst the Cascade Mountains. With a volume of 0.6 cubic miles (2.5 cu km), Mount Lassen is the largest lava plug dome in the world.

Mount Lassen reaches a summit of 10,457 feet (3,187 m) as it looks out over the northern end of the Sacramento Valley. The last major eruption occurred in 1914, which was followed by a number of smaller eruptions up through 1921.
