Location: Mendocino County, approximately 8 miles southeast of Covelo, California.
Area Description: The wilderness area is cooperatively managed by the Mendocino National Forest and the BLM and totals 53,887 acres. BLM manages 17,365 acres of these lands. The wilderness is comprised of several long, brush covered ridges (Long Doe, Horse Pasture, Thatcher, and Bentley). The topography consists of relatively flat ridge tops with westerly-facing, brush-covered slopes. Elevations run from about 1,200 feet to Thatcher Butte at 4,600 feet. Vegetation varies from dense chaparral/chamise to a few small open grassland/oak meadows. There are some patches of timber along the higher elevations of Hayshed and Thatcher Creeks. The Middle Fork Eel Wild and Scenic River flows through the northern portion of the area.
Notable wildlife includes the endangered bald eagle and peregrine falcon. Anadromous fish (Chinook salmon and steelhead) use the Middle Fork Eel River and its tributaries for spawning and rearing
Getting There: Access to the wilderness area is from U.S. Highway 101 at Highway 162 (between Laytonville and Willits), easterly past Covelo for several miles, then south on Etsel Ridge Road, right on Thatcher Butte Road, and then to Horse Pasture Ridge Road.
Nonfederal Lands: One parcel of 200 acres is surrounded by wilderness. Please respect private land boundaries.
Additional Information: Signs indicating the wilderness boundary have been posted. Mechanized or motorized vehicles are not allowed in this wilderness area, except for private landowners access to his property. Hunting and fishing are allowed under state and local laws. Pets are allowed, and must be under the owners control at all times. Camping is allowed, limited to 14 days. Campfires are allowed unless prohibited during seasonal fire restrictions. Gathering wood for campfires, when permitted, is limited to dead and down materials. Do not cut live vegetation.
The BLM encourages all travelers exploring public lands, to use propylene glycol based antifreeze/coolant in their touring and recreation vehicles. Proven safer, it will have minimal impacts on the wildlife and the environment should a leak occur.
