Carson–Iceberg Wilderness
The Carson–Iceberg Wilderness is a federal wilderness area located northeast of Stockton, California. It encompasses and was designated by the California Wilderness Act of 1984. It protects an area of High Sierra landscape with elevations from to along the Sierra Mountains from Ebbetts Pass to Sonora Pass in the south. The US Forest Service manages the wilderness which is in both the Stanislaus National Forest and the Humboldt–Toiyabe National Forest. Located in the wilderness are the headwaters of the Carson River draining the east side of the crest, as well as the North and Middle Forks of the Stanislaus River on the west slopes. The name Carson–Iceberg comes from two prominent geographical features: the Carson River (named for noted scout and explorer Kit Carson) and the distinctive granite formation called "The Iceberg" on the southern boundary near Clark Fork Road. Historical highlights: Jedediah Smith crossed the Sierra Nevada Range near Ebbetts Pass sometime i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bartleson–Bidwell Party
In 1841, the Bartleson–Bidwell Party, led by Captain John Bartleson and John Bidwell, became the first American emigrants to attempt a wagon crossing from Missouri to California. Beginnings In the winter of 1840, the Western Emigration Society was founded in Missouri, with 500 pledging to trek west into Mexican California. Members included Baldridge, Barnett, Bartleson, Bidwell and Nye. Organized on 18 May 1841, Talbot H. Green was elected president, John Bidwell secretary, and John Bartleson captain. The group joined Father Pierre Jean De Smet's Jesuit missionary group, led by Thomas F. Fitzpatrick, westward across South Pass along the Oregon Trail. That trail took them past Courthouse and Jail Rocks, Chimney Rock, Scotts Bluff, Fort Laramie, and Independence Rock. The Bartleson-Bidwell party separated from Fitzpatrick, and the missionary group, at Soda Springs on 11 Aug. The Trail The western Emigration Society had resolved to follow the route suggested by Dr. Jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Nevada Yellow-legged Frog
The Sierra Nevada yellow-legged frog or Sierra Nevada Mountain yellow-legged frog (''Rana sierrae'') is a true frog endemic to the Sierra Nevada of California and Nevada in the United States. It was formerly considered ''Rana muscosa'' until a 2007 study elevated the more central and northern populations to full species status, restricting ''R. muscosa'' to the southern Sierra Nevada and southern California. Once abundant in the Sierra Nevadas, the ecological effects of their loss have been significant as they were a keystone species and important for nutrient and energy cycling in the aquatic and terrestrial ecosystems. Description The Sierra Nevada yellow-legged frog is one of the two mountain yellow-legged frog species which include Rana sierrae and Rana muscosa. The Sierra Nevada yellow-legged frog (Rana sierrae) is very similar in appearance to the southern mountain yellow-legged frog (Rana muscosa), with which it was formerly identified. The two were separated into differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lahontan Cutthroat Trout
Lahontan cutthroat trout (''Oncorhynchus clarkii henshawi'') is the largest subspecies of cutthroat trout, and the state fish of Nevada. It is one of three subspecies of cutthroat trout that are listed as federally threatened. Natural history The Lahontan cutthroat is native to the drainages of the Truckee River, Humboldt River, Carson River, Walker River, Quinn River and several smaller rivers in the Great Basin of North America. These were tributaries of ancient and massive Lake Lahontan during the ice ages until the lake shrank to remnants such as Pyramid Lake and Walker Lake about 7,000 years ago, although Lake Tahoe—from which the Truckee flows to Pyramid Lake—is still a large mountain lake. In this sense, Lahontan cutthroats essentially evolved in inland ocean-like conditions. Here, Lahontan cutthroats became a large (up to 1 m or 39 in) and moderately long-lived predator of chub suckers, and other fish as long as 30 or . The trout was able to remain ...

US Fish And Wildlife Service
The United States Fish and Wildlife Service (USFWS or FWS) is an agency within the United States Department of the Interior dedicated to the management of fish, wildlife, and natural habitats. The mission of the agency is "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people." Among the responsibilities of the USFWS are enforcing federal wildlife laws; protecting endangered species; managing migratory birds; restoring nationally significant fisheries; conserving and restoring wildlife habitats, such as wetlands; helping foreign governments in international conservation efforts; and distributing money to fish and wildlife agencies of U.S. states through the Wildlife Sport Fish and Restoration Program. The vast majority of fish and wildlife habitats are on state or private land not controlled by the United States government. Therefore, the USFWS works closely with private groups ...

Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.

Paiute Cutthroat Trout
Paiute cutthroat trout (''Oncorhynchus clarkii seleniris'') is one of fourteen subspecies of cutthroat trout. Paiute Cutthroat are native only to Silver King Creek, a headwater tributary of the Carson River in the Sierra Nevada, in California. This subspecies is named after the indigenous Northern Paiute peoples. Paiute cutthroat trout are endemic to and protected within the Carson Ranger District of the Humboldt-Toiyabe National Forest. The Carson River lies within the Great Basin interior drainage system, within the historic range of Lahontan cutthroat trout (''Oncorhynchus clarki henshawi''). Natural history It is believed that a sub-population of Lahontan cutthroats became isolated in Silver King Creek above Silver King Canyon Gorge after erosion made the gorge impassable to trout swimming upstream, probably between 5,000 and 8,000 years ago. The upstream population then adapted to local conditions independent of the larger population below that had evolved in pluvial ...

Bull Run Lake, Carson-Iceberg Wilderness
A bull is an intact (i.e., not castrated) adult male of the species '' Bos taurus'' (cattle). More muscular and aggressive than the females of the same species (i.e., cows), bulls have long been an important symbol in many religions, including for sacrifices. These animals play a significant role in beef ranching, dairy farming, and a variety of sporting and cultural activities, including bullfighting and bull riding. Due to their temperament, handling requires precautions. Nomenclature The female counterpart to a bull is a cow, while a male of the species that has been castrated is a ''steer'', '' ox'', or ''bullock'', although in North America, this last term refers to a young bull. Use of these terms varies considerably with area and dialect. Colloquially, people unfamiliar with cattle may refer to both castrated and intact animals as "bulls". A wild, young, unmarked bull is known as a ''micky'' in Australia.Sheena Coupe (ed.), ''Frontier Country, Vol. 1'' (Weldon ...

Cercocarpus Ledifolius
''Cercocarpus ledifolius'' is a North American species of Mountain-mahogany, mountain mahogany known by the common name curl-leaf mountain mahogany. It is widespread across much of the Western United States as well as Baja California in Mexico. It can be found at elevations ranging from 600 to 3,000 m (2,000 to 9,800 ft) elevation, with the preferred altitude varying depending on the region. It prefers shallow, well-drained soils with a sandy or grainy consistency, and is generally found in areas which receive low annual precipitation (15–26 cm). This makes it common on low mountains and slopes, where it grows in scattered groves among other drought-resistant species such as Pinyon pine, Pinyon Pines, Junipers and Sagebrush ecosystems. Description ''Cercocarpus ledifolius'' is a large, densely branching tree which can reach heights of 11 m (35 ft), although it is not uncommon to find the adult plant as a shrub as short as 1 m (3 ft).

Lodgepole Pine
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches are covered with short shoots that are easy to ...
