It is named after pioneer Peter Lassen, who mined, ranched and promoted the area to emigrant parties in the 1850s.

Lassen National Forest is located about 80 miles (130 km) east of Red Bluff, California.

It is bordered by Sierra Nevada mountain range to the south, the Modoc Plateau to the east and California's Central Valley to the west.

The forest has two major river systems as well as many lakes, cinder cones and lava flows.

Sierra Nevada mixed conifer forests (Coast Douglas-fir (Pseudotsuga menziesii var.

Lassen was murdered by an unknown person in the Black Rock Desert, Nevada Territory,[5] two months after being profiled by Hutchings' Illustrated California Magazine.

Lassen, Edward Clapper and Americus Wyatt, were on a silver mining expedition, camped in the Black Rock Desert north of Virginia City, Nevada Territory.

Officially a band of Paiute Native Americans received blame but few pioneers believed the story.

Lassen was born on October 31, 1800, in Farum, Denmark, and emigrated to Mexican California around 1840 from the Oregon Territory.

Like Sutter, he acquired Mexican citizenship (1844) and applied for a land grant (1843)[7] of 5 square leagues[8] on the south bank of Deer Creek in what is now Butte County, California.

This grant provided access to the Sacramento River, an important issue during the pioneer period for transportation of goods and people.

[10] The first federal forest reserves were created soon after President William Henry Harrison signed the repeal into law.

Section 24 of the act authorized the President of the United States to set aside public lands as forest reserves without further permission from Congress.

In addition to Harrison, President William McKinley set aside forest lands, as did President Theodore Roosevelt, until Congress put a stop to the practice in 1907, by banning additional set asides in six western states.

[16] Later, in 1939, Interior Secretary Harold Ickes proposed the opposite-of combining the national parks and forests into an agency that would take a preservationist approach.

Built on what was once the roadbed of Southern Pacific's 130-mile (210 km) Fernley and Lassen Branch Railway, it has been converted to a riding and hiking trail.

The trail goes through Susanville and past the north side of Lassen Volcanic National Park.

[21] The Forest Service maintains 63 developed recreational sites and an indeterminate number of primitive campgrounds.

Their father is the son of OR7, a wolf with a tracking device that was the first of its kind in almost a century to migrate into California from Oregon.

He lived his remaining years at the University of California's Anthropology Museum on Parnassus Heights in San Francisco, under the sponsorship of anthropologist Alfred Kroeber.

The university had no protocol for keeping a living museum exhibit, so Kroeber arranged for Ishi's employment as assistant janitor.

Ishi was Yahi, the southernmost division of the Yana and had spent the majority of his life in hiding in the rugged Deer Creek territory north of Oroville.

In 1984 Congress established the 41,100-acre (16,600 ha)[25] Ishi Wilderness in the dry, rugged, volcanic terrain, where the last band of Southern Yanas had sought refuge.

(Visitors to this wilderness are advised by the United States Forest Service to visit only during cooler months because of a lack of water during the summer.)

[26] In the 1920s, the managers of the Forest Service engaged in both an internal and external struggle regarding the agency's mission.

Caribou Primitive Area received greater protection in 1939, when Interior Secretary Harold Ickes sought to convince President Franklin D. Roosevelt to combine the Forest Service and the National Park Service into a new agency under the management of the United States Department of Interior.
