What Is Lassen County California Known For?

Lassen County is known for its unspoiled and dramatic forested mountains, volcanoes, hydrothermal areas, and high-elevation lakes. Lassen is also known for its fascinating Native American and frontier history. Here are some prominent natural and historical features of Lassen County.

  • Volcanoes
  • Hydrothermal and geothermal areas
  • Alpine lakes
  • Native American and frontier history


Lassen is renowned for the volcanoes that dot the northeastern region of the county. The volcanoes are part of the southern Cascade Mountains, and include the four basic volcano types:

  • shield,
  • plug dome,
  • cinder cone,
  • stratovolcano.

Many volcanoes in Lassen County are active, including Lassen Volcano Center and Lassen Peak.

Lassen Peak is probably the most famous volcano in Lassen County. This 10547-foot volcanic peak consists of igneous rock. Lassen Peak is the largest plug dome volcano on earth and is active, having last erupted about a century ago.  

Hydrothermal And Geothermal Areas

Lassen County is known for its otherworldly geothermal and hydrothermal areas. These areas include lava gas vents, steam vents, boiling pools, and mud pots.

The bizarre volcanic phenomena are created when snow melt and rainwater flow underground. The water then gets heated by magma and is forced above ground again as boiling water, mud, gas, and steam.

Alpine Lakes

There is a close association in the popular imagination between Lassen and pristine lakes in the high, snow-tipped mountains of the Cascades. The lakes are in the eastern half of Lassen County and are part of the Great Basin region.  

Eagle Lake is one of the biggest and most well-known lakes in Lassen County.

This stunning lake is one of the largest in California, and is perched 5100-feet above sea level. Eagle Lake is set against the background of stoic sagebrush hills along its northwestern banks and stands of pine, juniper, and cypress cover the lake’s southeastern shores.

The lake is ideally suited for summer outdoor recreational activities like swimming, hiking, fishing, and picnicking.

Native American And Frontier History

Lassen County is known for its intriguing ancient and modern history.

Native American groups like the Maidu, Yana, Atsugewi, and Yahi inhabited the local area for millennia.

These Native American peoples lived in the region during the spring and summer months when they harvested plants for food and medicine and for making baskets and other woven artifacts. The Yana, Maidu, Yahi, and Atsugewi also hunted deer populations migrating through the valleys and meadows of Lassen during the warmer months of the year.

People of European descent started exploring and settling in this part of Northern California in increasing numbers from the mid-19th Century. Fur trappers and traders were among the first non-natives to arrive in the area.

The first European towns were constructed during the local gold rush during the 1880s. These settlements grew more rapidly soon afterward when the railroads made their way into the region. The railroads also facilitated the development of the logging industry. Logging shaped the landscape and economy of Lassen County for much of the 20th-Century.

What’s In Lassen County?

Numerous nature parks and reserves in Lassen showcase the county’s wild and wondrous natural beauty. Lassen County also has places like museums that exhibit and interpret the history of the local area.

Lassen Volcanic National Park

Lassen Volcanic National Park is the jewel of Lassen County. The park is near the city of Susanville and covers an area of 166-square miles.

Most of the volcanoes in Lassen County are within the borders of Lassen Volcanic National Park, including the famed Lassen Peak, Lassen Volcanic Center, and Cinder Cone. There are also hydrothermal and geothermal areas dotted throughout the park, such as Sulfur Works and Cold Boiling Lake.

In addition to volcanic peaks, Lassen Volcanic National Park has verdant forests of pine and fir trees and wildflower meadows in the springtime. Kings Creek and a host of other crystalline streams of fresh mountain water flow in the park.

The mesmerizing Manzanita Lake is another prominent feature of Lassen Volcanic National Park’s landscape. This 50-acre natural lake formed roughly 300 years ago when rockfall inadvertently created a dam wall across Manzanita Creek.  

Part of the Lassen Volcanic National Park still carries the scars of the most recent eruption of Lassen Peak about a century ago. This zone is called the Devastated Area and has a dedicated walking trail for visitors to view and interpret the effects of the volcanic eruption.

Beyond these natural wonders, the Kohm Yah-mah-nee Visitor Center and the Loomis Museum in the Lassen Volcanic National Park showcase the social and cultural history of the local area.

National Forests

Magnificent stands of pine and fir trees surround Lassen County. Much of the county’s arboreal bounty is protected inside the boundaries of four national forests:

  • Lassen National Forest,
  • Plumas National Forest,
  • Toiyabe National Forest,
  • Modoc National Forest.

The US Forest Service (an agency of the US Department of Agriculture) manages these national forests, and logging occurs in some areas. However, the national forests contain large expanses of designated wilderness, where one can experience the untouched beauty of Lassen County’s forests.

There are also three remarkable wilderness areas within the boundaries of Lassen National Forest. These wild and untouched sections of the national forest encompass an area of roughly 78 000 acres.
