Lassen National Forest - Southern Cascades
Lassen National Forest is a national forest of 1,700 square miles (4,300 km2) in northeastern California. It is named after pioneer Peter Lassen, who mined, ranched and promoted the area to emigrant parties in the 1850s, before he was murdered, possibly by a disgruntled emigrant.
Lassen National Forest is located about 80 miles (130 km) east of Red Bluff, California. It is generally bounded by Sierra Nevada mountain range to the south, the Modoc Plateau to the east and California's Central Valley to the west. The forest is in parts of Lassen, Shasta, Tehama, Plumas, and Butte counties. Forest headquarters is located in Susanville, California. There are local ranger district offices in Chester, Fall River Mills, and Susanville.
The forest was formed in 1905 when it was named one of the National Forest Reserves, which evolved into the National Forest system.
The forest was first named the Lassen Peak Forest Reserve because of Lassen Peak, a volcano which is in the southernmost portion of the Cascade Range volcanoes. Mt. Lassen erupted with explosive force in 1915. The forest surrounds Lassen Volcanic National Park. The forest has two major river systems as well as many lakes, cinder cones and lava flows.
Surveys estimate the forest contains 92,000 acres (370 km2) of old growth. Sierra Nevada mixed conifer forests (Coast Douglas-fir (Pseudotsuga menziesii var. menziesii), Ponderosa Pine (Pinus ponderosa), and White Fir (Abies concolor)), Jeffrey Pine (Pinus jeffreyi) forests, Red Fir (Abies magnifica) forests, and Lodgepole Pine (Pinus contorta) forests are the most common types. It is a major source of lumber products.
