Lassen National Forest (LNF - Forest #06) "Susanville" KMB 6-9-0

The forest was formed in 1905 when it was named one of the Forest Reserves, which were all renamed "National Forests" in 1907. It is named after pioneer Peter Lassen, who mined, ranched and promoted the area to emigrant parties in the 1850s. The size of the Lassen National Forest is 1.2 million acres. The Forest lies at the heart of one of the most fascinating areas of California, called the Crossroads. Here the granite of the Sierra Nevada, the lava of the Cascades and the Modoc Plateau, and the sagebrush of the Great Basin meet and blend. It is an area of great variety, greeting visitors and residents alike with a wide array of recreational opportunities and adventures. Fishing, hunting, camping, hiking, bicycling, boating, snowmobiling, cross-country skiing, and just exploring and learning about nature are among the many popular pastimes.

Within the Lassen National Forest you can explore a lava tube or the land of Ishi, the last survivor of the Yahi Yana Native American tribe; watch pronghorn antelope glide across sage flats or an osprey snatch fish from lake waters; drive four-wheel trails into high granite country appointed with sapphire lakes or discover spring wildflowers on foot.

The forest has 92,000 acres of old growth. The common tree species are Douglas fir (Pseudotsuga menziesii var. menziesii), Ponderosa pine (Pinus ponderosa), White Fir (Abies concolor), Jeffrey pine (Pinus jeffreyi), Red fir (Abies magnifica), and Lodgepole pine (Pinus contorta).

The Forest is divided into the Almanor (District 1), Hat Creek (District 3) and Eagle Lake (District 8) Ranger Districts, with the Forest Supervisor's Office in Susanville.
