Mount Lassic Wilderness

General Maps Contacts Area Management Wilderness Laws


The United States Congress designated the Mount Lassic Wilderness (map) in 2006 and it now has a total of 7,295 acres. All of this wilderness is located in California and is managed by the Forest Service.


The Mount Lassic Wilderness, located approximately 20 miles northeast of Garberville and 8 miles west of Ruth Reservoir in Humboldt and Trinity counties, is a picturesque cluster of peaks offering impressive views of the Coast Range. The area contains unique rock formations such as Mount Lassic and Red Lassic that are visible from as far away as the King Range Wilderness to the west and the Yolla Bolly-Middle Eel Wilderness to the south. Vernal pool fairy shrimp live in the area's seasonal wetlands. Vernal pools usually occur at much lower elevations (most notably in the Central Valley), thus making this habitat extremely unique. Unusual soils make this area fascinating to botanists, and six rare plant species have been identified in the region. Other species include northern spotted owl, blue grouse, marten, fisher, and goshawk. Old-growth forests of Douglas fir, incense cedar, and Jeffrey pine cover much of the area.
