San Gabriel Wilderness
The San Gabriel Wilderness is a wilderness area created in 1968 of more than 36,118 acres (150 km) within the Angeles National Forest and San Gabriel Mountains National Monument. The area lies on the southern slopes of the San Gabriel Mountains, between the Angeles Crest and the West Fork of the San Gabriel River. The area was originally set aside as the Devils Canyon-Bear Canyon Primitive Area of . The San Gabriel Mountains were first preserved by the federal government in 1892 as the San Gabriel Timberland Reserve, established by U.S. President Benjamin Harrison and influenced by  California conservationists, Abbot Kinney and John Muir. This forest reserve would later become part of the Angeles National Forest in which the San Gabriel Wilderness is now located. Recreation. Permits are not required to enter the San Gabriel wilderness. Access trails. The following trails provide access: Hiking Trails within the Wilderness Area. Hiking trails in the Designated Wilderness are built and maintained utilizing hand tools and materials which are strictly limited in terms of environmental impact. The use of chainsaws to remove trees that are down across trails is prohibited, requiring the use of crosscut saws, block-and-tackle chains  and ropes to pull trees off of trails, griphoists, and other mechanical tools which do not produce noise or petroleum-based pollutants. In addition, wheeled tools and equipment are not permitted to be used in the Designated Wilderness, neither for trail maintenance nor for recreation, causing the wilderness to be classified for pedestrian and equestrian use only with mountain biking prohibited. Blasting to remove rock outcrops is prohibited, as is the use of fire-fighting tools like tractors, Phos-Chek air drops, Tovex Firebreak II explosives, and chainsaws to cut fire lines. Everything must be done by hand, even when  fighting fires within the Designated Wilderness. The people who maintain hiking trails within the San Gabriel Designated Wilderness attempt to achieve a passable hiking experience within the wilderness that does not appear to be too greatly unnatural. To achieve such an effect, tree limbs and branches that must be cut back are finished with an effort to appear natural, bucked tree trunks that are removed from the trail are relocated so that they appear at a distance and do not look to have been cut by people, and even sawdust from crosscut saws will be collected and buried off of  the trail.
