Title: Protected areas of the Sierra Nevada
Content:  The protected areas of the Sierra Nevada, a major mountain range located in the U.S. states of California and Nevada, are numerous and highly diverse. Like the mountain range itself, these areas span hundreds of miles along the length of the range, and over 14,000 feet of elevation from the lowest foothills to the summit of Mount Whitney. The Sierra Nevada, as a natural region, does not have exactly defined borders. In particular, to the north, there is a wide transition zone where the Cascade Range and the Sierra Nevada meet. As a result, it is difficult to delineate a border between these two mountain ranges. This list uses the common definition of the Sierra Nevada as the mountain range extending from Fredonyer Pass in the north to Tehachapi Pass in the south. It is also difficult to delineate between the Sierra Nevada mountains, the range's foothills, and the Central Valley; this article also considers any elevated and hilly terrain east of the flat Central Valley to be part of the range. Areas outside those bounds may also be included if they are widely associated with the Sierra Nevada.
Title: Sierra Nevada
Content:  The Sierra Nevada's irregular northern boundary stretches from the Susan River and Fredonyer Pass to the North Fork Feather River. It represents where the granitic bedrock of the Sierra Nevada dives below the southern extent of Cenozoic igneous surface rock from the Cascade Range. It is bounded on the west by California's Central Valley, on the east by the Basin and Range Province, and on the southeast by the Mojave Desert. The southern boundary is at Tehachapi Pass. Physiographically, the Sierra is a section of the Cascade–Sierra Mountains province, which in turn is part of the larger Pacific Mountain System physiographic division. The California Geological Survey states that "the northern Sierra boundary is marked where bedrock disappears under the Cenozoic volcanic cover of the Cascade Range."
Title: Western Nevada
Content:  Western Nevada encompasses the western edge of the state, with the term generally applied to areas within 100 mi of the California border, from Mineral County northward. On the west along the California border, the Sierra Nevada mountains rise sharply from the Great Basin desert floor. Basin and Range Province topography extends east from the Sierras, with mountain ranges such as the Virginia Range, Pah Rah Range and Pine Nut Mountains separating the more densely populated Sierra front with the desert plains to the east. The mountains act as a second rain shadow for Pacific storms rolling east. Three rivers flow off the Sierras to the Great Basin — the Truckee River, Carson River and Walker River. The Truckee Canyon through the Virginia and Pah Rah mountains serves as the route for Interstate 80 between Fernley and Reno. Pyramid Lake and Washoe Lake collect water in their respective endorheic basins, and Lake Lahontan impounds the Carson River to distribute water for irrigation in Churchill County.
Title: Sierra Nevada
Content:  The Sierra Nevada lies primarily in central and eastern California, with the Carson Range, a small but historically important spur, extending into Nevada. West-to-east, the Sierra Nevada's elevation increases gradually from 500 ft in the Central Valley to more than 14000 ft atop the highest peaks of its crest 50-75 mi to the east. The east slope forms the steep Sierra Escarpment. Unlike its surroundings, the range receives a substantial amount of snowfall and precipitation due to orographic lift.
Title: List of plants of the Sierra Nevada (U.S.)
Content:  The Sierra Nevada's immense size in length and height, geological age, and wide variety of ecosystems and habitats present, make them home to one of the most diverse collections of distinct plant species in the United States. The Sierras are bordered by: the Great Basin in rain shadow on the east; the Cascade Range on the north; the Central Valley—San Joaquin Valley on the west; the Tehachapi Mountains linking the Transverse Ranges on the southwest; and the Mojave Desert on the south.
Title: Sierra Nevada
Content:  The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs 400 mi north-south and is approximately 70 mi across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at 14505 ft, the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia,

Content:  The Sierra Nevada, also known locally as the "Sierra", is a mountain range running 400 mi north-to-south along eastern California, and occasionally into western Nevada. The name "Sierra Nevada" is Spanish, translating as "Snowy (Mountain) Range".

Content:  Toro (4729) and Pico Mucuñuque (4609). The Sierra Nevada is separated from the Sierra La Culata, other Cordilleran massif of Andean mountain range, by depression of the Chama River in the north, while the northeast makes the valley of the River Santo Domingo, from the Kettle Mucubají to the dam José Antonio Páez. In the southwest, the boundary of the park forms the valley of River Nuestra Señora, left bank tributary of the Chama River, downstream from the city of Ejido. The park is in two major mountain ranges: the Sierra Nevada de Mérida and the Sierra de Santo Domingo, which are characterized by high peaks, glacial valleys and river valleys. Most rivers are the Chama, Albarregas and Mucujún flowing into Lake Maracaibo. Meanwhile, the Orinoco

Several rivers drain from the Sierra Nevada eastward, including the Walker, Truckee, and Carson rivers. All of these rivers are endorheic basins, ending in Walker Lake, Pyramid Lake, and the Carson Sink, respectively. However, not all of Nevada is within the Great Basin. Tributaries of the Snake River drain the far north, while the Colorado River, which also forms much of the boundary with Arizona, drains much of southern Nevada. The mountain ranges, some of which have peaks above 13000 
Title: Nevada
Content:  Nevada is a state in the Western region of the United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the 7th-most extensive, the 19th-least populous, and the 9th-least densely populated of the U.S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area, including three of the state's four largest incorporated cities. Nevada's capital is Carson City while the largest city is Las Vegas. Nevada is officially known as the "Silver State" because of the
