Lyell Canyon
Lyell Canyon is a sub-alpine meadow in Yosemite National Park south of Tuolumne Meadows. For 13 kilometers (8 statute miles) most of the canyon has an approximate elevation of 2 700 meters (8,850 feet), and then rapidly climbs to 3 370 meters (11,056 feet) to Donohue Pass, below Donohue Peak – which marks the eastern boundary of Yosemite. The valley at the base is relatively flat and wide, following the Lyell Fork of the Tuolumne River through an open meadow and wooded areas. The Lyell Fork eventually meets with Tuolumne River. The canyon as well as Mount Lyell to the west is named after Charles Lyell, a well-known 19th century geologist and friend of Charles Darwin. The canyon is an easy hike from Tuolumne Meadows campground. The John Muir Trail and the Pacific Crest Trail both route through the canyon. The trail is popular for hikers as an easy way to view surrounding mountains, a waterfall and Sierra wildflowers. External links Yosemite Hikes See also * Lyell Meadow ...

Sub-alpine Meadow
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tuolumne Meadows
Tuolumne Meadows () is a gentle, granitic dome, dome-studded, sub-alpine meadow area along the Tuolumne River in the eastern section of Yosemite National Park in the United States. Its approximate location is . Its approximate elevation is . The term ''Tuolumne Meadows'' is also often used to describe a large portion of the Yosemite National Park, Yosemite high country around the meadows, especially in context of rock climbing. Natural history The meadow vegetation is supported by shallow groundwater. The water comes from 1,000 mm (39 inches) of precipitation annually, predominantly in the form of snow. Water arises from snowmelt and hill-slope aquifers, and flows through the Tuolumne River, Budd Creek, Delaney Creek, and Unicorn Creek. In spring, as soon as the snow melts, it is not uncommon to see large areas of the meadows flooded and practically transformed into lakes. While the mountains of the Sierra near the meadows have had some permanent snowfields, in the summer they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tuolumne River
The Tuolumne River ( Yokutsan: ''Tawalimnu'') flows for through Central California, from the high Sierra Nevada to join the San Joaquin River in the Central Valley. Originating at over above sea level in Yosemite National Park, the Tuolumne drains a rugged watershed of , carving a series of canyons through the western slope of the Sierra. While the upper Tuolumne is a fast-flowing mountain stream, the lower river crosses a broad, fertile and extensively cultivated alluvial plain. Like most other central California rivers, the Tuolumne is dammed multiple times for irrigation and the generation of hydroelectricity. Humans have inhabited the Tuolumne River area for up to 10,000 years. Prior to the arrival of Europeans, the river canyon provided an important summer hunting ground and a trade route between Native Americans in the Central Valley to the west and the Great Basin to the east. First named in 1806 by a Spanish explorer after a nearby indigenous village, the Tuolumne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Lyell (California)
Mount Lyell is the highest point in Yosemite National Park, at . It is located at the southeast end of the Cathedral Range, northwest of Rodgers Peak (California), Rodgers Peak. The peak as well as nearby Lyell Canyon is named after Charles Lyell, a well-known 19th century geologist. The peak had one of the last remaining glaciers in Yosemite, Lyell Glacier. The Lyell Glacier is currently considered to be a permanent ice field, not a living glacier. Mount Lyell divides the Tuolumne River watershed to the north, the Merced River, Merced to the west, and the Rush Creek drainage in the Mono Lake Basin to the southeast. Climbing The most common approach to Mount Lyell is from Tuolumne Meadows on a highly traveled section of the John Muir Trail. The round trip is approximately and involves of elevation gain when starting from the Tuolumne Wilderness Office.

Charles Lyell
Sir Charles Lyell, 1st Baronet, (14 November 1797 – 22 February 1875) was a Scottish geologist who demonstrated the power of known natural causes in explaining the earth's history. He is best known as the author of ''Principles of Geology'' (1830–33), which presented to a wide public audience the idea that the earth was shaped by the same natural processes still in operation today, operating at similar intensities. The philosopher William Whewell termed this gradualistic view "uniformitarianism" and contrasted it with catastrophism, which had been championed by Georges Cuvier and was better accepted in Europe. The combination of evidence and eloquence in ''Principles'' convinced a wide range of readers of the significance of " deep time" for understanding the earth and environment. Lyell's scientific contributions included a pioneering explanation of climate change, in which shifting boundaries between oceans and continents could be used to explain long-term variati ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Crest Trail
The Pacific Crest Trail (PCT), officially designated as the Pacific Crest National Scenic Trail, is a long-distance hiking and equestrian trail closely aligned with the highest portion of the Cascade and Sierra Nevada mountain ranges, which lie east of the U.S. Pacific coast. The trail's southern terminus is next to the Mexico–United States border, just south of Campo, California, and its northern terminus is on the Canada–US border, upon which it continues unofficially to the Windy Joe Trail within Manning Park in British Columbia; it passes through the states of California, Oregon, and Washington. The Pacific Crest Trail is long and ranges in elevation from roughly above sea level near the Bridge of the Gods on the Oregon–Washington border to at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks. Its midpoint is near Chester, California (near Mt. Lassen), where the Sierra and Cascade mountain ranges meet. It was d ...
