Context paragraphs:
Public Law 94-567: Public Law 94-567 is a 1976 Federal law that established a number of new designated Wilderness Areas on National Park Service lands.  Signed into law by President Gerald Ford on October 20, 1976, the new statute added almost 900,000 acres of wilderness into the National Wilderness Preservation System.  While the majority of designated Wilderness Areas at the time were located in National Forests, this was one of the first laws to formally establish wilderness areas in National Parks and Monuments.

Sylvania Mountains Wilderness: The Sylvania Mountains Wilderness is a federally designated wilderness area located 30 mi east of Bishop in the state of California.  The wilderness is 18,677acres in size and is managed by the Bureau of Land Management (BLM).  The California Desert Protection Act of 1994 created the Sylvania Mountains Wilderness and was added to the National Wilderness Preservation System.  The wilderness is bordered by Nevada stateline on the east, Piper Mountain Wilderness on the west and Death Valley National Park to the south.

California protected areas: Obtaining an accurate total of all protected land in California and elsewhere is a complex task.  Many parcels have inholdings, private lands within the protected areas, which may or may not be accounted for when calculating total area.  Also, occasionally one parcel of land is included in two or more inventories.  Over 90% of Yosemite National Park for example, is listed both as wilderness by the National Wilderness Preservation System, and as national park land by the National Park Service.  The Cosumnes River Preserve is an extreme example, owned and managed by a handful of public agencies and private landowners, including the Bureau of Land Management, the County of Sacramento and The Nature Conservancy.  Despite the difficulties, the CPAD gives the total area of protected land at 49000000 acre , or 46.7% of the state (not including easements); a considerable amount for the most populous state in the country.

Caribou Wilderness: The Caribou Wilderness is a federally designated wilderness area created by the Wilderness Act of 1964 and is part of the National Wilderness Preservation System.  It is located 60 mi east of Redding in the state of California, USA.  The Caribou Wilderness comprises 20546 acre and is adjacent to the east side of Lassen Volcanic National Park.  Although the park (which includes its own Lassen Volcanic Wilderness area) is surrounded by Lassen National Forest, it is managed separately by the National Park Service, whereas the U.S. Forest Service manages the wilderness.

Sawtooth Wilderness: The Sawtooth Wilderness ( ) is a federally-protected wilderness area that covers 217088 acre of the state of Idaho.  Managed by the U.S. Forest Service in the U.S. Department of Agriculture, it was designated the Sawtooth Primitive Area in 1937 to preserve the exceptional scenic beauty of the Sawtooth Mountains.  On August 22, 1972 Public Law 22-400 designated the Primitive Area as the Sawtooth Wilderness and part of the newly created Sawtooth National Recreation Area.  As part of the National Wilderness Preservation System, the Sawtooth Wilderness is an area where human development and use are restricted and people are to remain only visitors.  According to the United States Environmental Protection Agency, the Sawtooth Wilderness has some of the clearest air in the lower 48 states.

National Wilderness Preservation System: The National Wilderness Preservation System (NWPS) of the United States protects federally managed wilderness areas designated for preservation in their natural condition.  Activity on formally designated wilderness areas is coordinated by the National Wilderness Preservation System.  Wilderness areas are managed by four federal land management agencies: the National Park Service, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management.  The term "wilderness" is defined as "an area where the earth and community of life are untrammeled by man, where man himself is a visitor who does not remain" and "an area of undeveloped Federal land retaining its primeval character and influence, without permanent improvements or human habitation, which is protected and managed so as to preserve its natural conditions."  As of 2015, there are 765 designated wilderness areas, totaling 109,129,657 acre , or about 4.5% of the area of the United States.

Hemingway–Boulders Wilderness: The Hemingway–Boulders Wilderness is a 67998 acre protected area in Sawtooth National Recreation Area, part of Sawtooth National Forest in Blaine and Custer counties, Idaho, United States.  The wilderness covers part of the Boulder Mountains and directly adjoins the Jim McClure–Jerry Peak Wilderness on its northeast side and is south of the White Clouds Wilderness, which it does not directly adjoin.  It is named for the Boulder Mountains and Ernest Hemingway, who was a resident of nearby Ketchum.  The area was added to the National Wilderness Preservation System on August 7, 2015 with the passage of the Sawtooth National Recreation Area and Jerry Peak Wilderness Additions Act, which was sponsored by Representative Mike Simpson and passed Congress without objection before being signed into law by President Barack Obama.

Shenandoah National Park: Shenandoah National Park (often ) is a national park that encompasses part of the Blue Ridge Mountains in the U.S. state of Virginia.  The park is long and narrow, with the broad Shenandoah River and Valley on the west side, and the rolling hills of the Virginia Piedmont on the east.  Although the scenic Skyline Drive is likely the most prominent feature of the park, almost 40% of the land area 79579 acre has been designated as wilderness and is protected as part of the National Wilderness Preservation System.  The highest peak is Hawksbill Mountain at 4051 ft .

Pignut Mountain: Pignut Mountain is a mountain in Rappahannock County, Virginia.  It is part of the Blue Ridge Mountains.  Its summit lies within Shenandoah National Park.

Darwin Falls Wilderness: The Darwin Falls Wilderness is the area adjacent to Darwin Falls, it has a unique location in the northern Mojave Desert, just west of Death Valley National Park.

The Darwin Falls Wilderness Area was founded on October 31, 1994 totaling up to 8,176 acres of land.  The Darwin Wilderness is made up of several distinct landmarks, including The Darwin Plateau, an area between The Inyo Mountains to the north, and the Coso Range to the south.  The wilderness area is also near the Darwin Hills, a mountain range in Inyo County and the Argus Range, west of the Panamint Range.
