Mount Lassic Wilderness
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.
