Question: What type of climate of California influences the climate of the Sierra Nevada?

The climate of the Sierra Nevada is influenced by the Mediterranean climate of California.  During the fall, winter and spring, precipitation in the Sierra ranges from 20 to 80 in (510 to 2,030 mm) where it occurs mostly as snow above 6,000 ft (1,800 m). Precipitation is highest on the central and northern portions of the western slope between 5,000 and 8,000 feet (1,500 and 2,400 m) elevation, due to orographic lift.:69 Above 8,000 feet (2,400 m), precipitation diminishes on the western slope up to the crest, since most of the precipitation has been wrung out at lower elevations. Most parts of the range east of the crest are in a rain shadow, and receive less than 25 inches of precipitation per year. Summers are dry with low humidity; however, afternoon thunderstorms are common, particularly during the North American Monsoon. Summer high temperatures average 42–90 °F (6–32 °C). Winters are comparatively mild, and the temperature is usually only just low enough to sustain a heavy snowpack; winter high temperatures at elevation average 35–15 °F (2 – −9 °C), and rarely dip below 0 °F (−18 °C).[citation needed] The growing season lasts 20 to 230 days, strongly dependent on elevation. The highest elevations of the Sierra have an alpine climate.

Question: What is the Sierra Nevada snowpack a a significant source of for California?

The Sierra Nevada snowpack is the major source of water and a significant source of electric power generation in California.  Many reservoirs were constructed in the canyons of the Sierra throughout the 20th century,  Several major aqueducts serving both agriculture and urban areas distribute Sierra water throughout the state. However, the Sierra casts a rain shadow, which greatly affects the climate and ecology of the central Great Basin. This rain shadow is largely responsible for Nevada being the driest state in the United States.

Question: What time period were the Martis people of Paleo-Indians in northcentral Sierra Nevada?

Archaeological excavations placed Martis people of Paleo-Indians in northcentral Sierra Nevada during the period of 3,000 BCE to 500 CE. The earliest identified sustaining indigenous people in the Sierra Nevada were the Northern Paiute tribes on the east side, with the Mono tribe and Sierra Miwok tribe on the western side, and the Kawaiisu and Tubatulabal tribes in the southern Sierra. Today, some mountain passes, such as Duck Pass with obsidian arrowheads, are artifact locations from historic intertribal trade route trails. The California and Sierra Native American tribes were predominantly peaceful, with occasional territorial disputes between the Paiute and Sierra Miwok tribes in the mountains. Washo and Maidu were also in this area prior to the era of European exploration and displacement.

Question: Who was in charge of a subgroup of the Bonneville Expedition?

In 1833, a subgroup of the Bonneville Expedition led by Joseph Reddeford Walker was sent westward to find an overland route to California. Eventually the party discovered a route along the Humboldt River across present-day Nevada, ascending the Sierra Nevada, starting near present-day Bridgeport and descending between the Tuolumne and Merced River drainage. The group may have been the first non-indigenous people to see Yosemite Valley. The Walker party probably visited either the Tuolumne or Merced Groves of Giant Sequoia, becoming the first non-indigenous people to see the giant trees, but journals relating to the Walker party were destroyed in 1839, in a print shop fire in Philadelphia.

Question: In what year did gold extraction turn to more difficult locations?

By 1853, most of the easily accessible gold had been collected, and attention turned to extracting gold from more difficult locations. Hydraulic mining was used on ancient gold-bearing gravel beds on hillsides and bluffs in the gold fields.:89 In hydraulic mining, a high-pressure hose directed a powerful stream or jet of water at gold-bearing gravel beds. By the mid-1880s, it is estimated that 11 million ounces (340 t) of gold (worth approximately US$15 billion at December 2010 prices) had been recovered by "hydraulicking". A byproduct of these extraction methods was that large amounts of gravel, silt, heavy metals, and other pollutants went into streams and rivers.:32–36 As of 1999[update], many areas still bear the scars of hydraulic mining, since the resulting exposed earth and downstream gravel deposits do not support plant life.:116–121

Question: What extraction methods caused pollution of streams and rivers?

Answer: hydraulicking

Question: What caused population growth in the western foothills of the Sierra Nevada?

The Gold Rush populated the western foothills of the Sierra Nevada, but even by 1860 most of the Sierra was unexplored. The state legislature authorized the California Geological Survey to officially explore the Sierra (and survey the rest of the state). Josiah Whitney was appointed to head the survey. Men of the survey, including William H. Brewer, Charles F. Hoffmann and Clarence King, explored the backcountry of what would become Yosemite National Park in 1863. In 1864 they explored the area around Kings Canyon.  In 1869, John Muir started his wanderings in the Sierra Nevada range, and in 1871 King was the first to climb Mount Langley and that year fishermen were the first to climb Mount Whitney.  From 1892–7 Theodore Solomons made the first attempt to map a route along the crest of the Sierra.

Question: When was the Valley and Mariposa Grove ceded to California?

The tourism potential of the Sierra Nevada was recognized early in the European history of the range.
Yosemite Valley was first protected by the federal government in 1864. The Valley and Mariposa Grove were ceded to California in 1866 and turned into a state park. John Muir perceived overgrazing by sheep and logging of Giant Sequoia to be a problem in the Sierra. Muir successfully lobbied for the protection of the rest of Yosemite National Park: Congress created an Act to protect the park in 1890. The Valley and Mariposa Grove were added to the Park in 1906. In the same year, Sequoia National Park was formed to protect the Giant Sequoia: all logging of the Sequoia ceased at that time.

Question: How many times did Congress debate to make Lake Tahoe a national park?

Between 1912 and 1918, Congress debated three times to protect Lake Tahoe in a national park. None of these efforts succeeded, and after World War II, towns such as South Lake Tahoe grew around the shores of the lake. By 1980, the permanent population of the Lake Tahoe area grew to 50,000, while the summer population grew to 90,000. The development around Lake Tahoe affected the clarity of the lake water. In order to preserve the lake's clarity, construction in the Tahoe basin is currently regulated by the Tahoe Regional Planning Agency.
