Yosemite National Park is a national park in California. It is bordered on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers 759,620 acres in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, groves of giant sequoia, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada.
Yosemite Valley is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California, United States. The valley is about 7.5 mi (12.1 km) long and 3,000–3,500 ft (910–1,070 m) deep, surrounded by high granite summits such as Half Dome and El Capitan, and densely forested with pines. The valley is drained by the Merced River, and a multitude of streams and waterfalls flow into it, including Tenaya, Illilouette, Yosemite and Bridalveil Creeks. Yosemite Falls is the highest waterfall in North America and is a big attraction, especially in the spring, when the water flow is at its peak. The valley is renowned for its natural environment and is regarded as the centerpiece of Yosemite National Park.
Half Dome is a quartz monzonite batholith at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half. It stands at nearly 8,800 feet above sea level and is composed of quartz monzonite, an igneous rock that solidified several thousand feet within the Earth. At its core are the remains of a magma chamber that cooled slowly and crystallized beneath the Earth's surface. The solidified magma chamber was then exposed and cut in half by erosion, therefore leading to the geographic name Half Dome.
John Muir, also known as "John of the Mountains" and "Father of the National Parks", was a Scottish-born American naturalist, author, environmental philosopher, botanist, zoologist, glaciologist, and early advocate for the preservation of wilderness in the United States.
Tuolumne Meadows is a gentle, 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 37°52.5′N119°21′W. Its approximate elevation is 8,619 feet (2,627 m). The term Tuolumne Meadows is also often used to describe a large portion of the Yosemite high country around the meadows, especially in context of rock climbing.
El Capitan is a vertical rock formation in Yosemite National Park, on the north side of Yosemite Valley, near its western end. The granite monolith is about 3,000 feet (914 m) from base to summit along its tallest face and is a world-famous location for big wall climbing, including the disciplines of aid climbing, free climbing, and more recently for free solo climbing.
Sierra National Forest is a U.S. national forest located on the western slope of the central Sierra Nevada in California, bounded on the northwest by Yosemite National Park and on the south by Kings Canyon National Park. The forest is known for its mountain scenery and beautiful lakes. Forest headquarters are located in Clovis, California. There are local ranger district offices in North Fork and Prather.
Nevada Barr is an American author of mystery fiction. She is known for her Anna Pigeon series, which is primarily set in a series of national parks and other protected areas of the United States.
The ecology of the Sierra Nevada, located in the U.S. states of California and Nevada, is diverse and complex. The combination of climate, topography, moisture, and soils influences the distribution of ecological communities across an elevation gradient from 500 to 14,500 feet. Biotic zones range from scrub and chaparral communities at lower elevations, to subalpine forests and alpine meadows at the higher elevations. Particular ecoregions that follow elevation contours are often described as a series of belts that follow the length of the Sierra Nevada. There are many hiking trails, paved and unpaved roads, and vast public lands in the Sierra Nevada for exploring the many different biomes and ecosystems.
The Ahwahnechee, Awani, or Ahwahnechee were an Indigenous people of California who historically lived in the Yosemite Valley. They were a band of Miwok people, specifically Southern Sierra Miwok.
The Regular Northwest Face of Half Dome was the first Grade VI big wall climbing route in the United States. It was first climbed in 1957 by a team consisting of Royal Robbins, Mike Sherrick, and Jerry Gallwas. Its current aid climbing rating is VI 5.9 A1 or 5.12 for the free climbing variation. It is recognized in the historic climbing text Fifty Classic Climbs of North America and considered a classic around the world.
Carl William Sharsmith was an American naturalist and Yosemite park ranger, notable for his knowledge and interpretation of the natural history of the Sierra Nevada. He taught botany at various universities, and was the first botanist to comprehensively document the alpine flora of the high Sierra Nevada.
Helen Katherine Myers Sharsmith was an American biologist.
George G. Anderson was a Scottish mountaineer who is best known for making the first ascent to the summit of Half Dome in Yosemite National Park in California, United States on October 12, 1875. During the climb, he drilled the holes which, after 1919, came to house the cables of the popular route up Half Dome. A pioneer without the benefit of modern climbing gear or techniques, Anderson worked barefoot, and placed iron spikes drilled into the rock for protection. The ascent took him days on end. His one-room log cabin, originally located at what is now Foresta just west of Yosemite Valley, was moved to the Pioneer Yosemite History Center in Wawona where it continues to be preserved.
Fairview Dome is a prominent granite dome in Yosemite National Park, located 1.8 miles (2.9 km) north of Cathedral Peak and 4 miles (6.4 km) west of Tuolumne Meadows. Near Fairview Dome is Marmot Dome, linked by an area called Razor Back. Northwest is Hammer Dome.
Beatrice "Bettie" Willard was an American botanist who specialized in studies on the ecology and botany of high alpine tundra, as well as arctic tundra. Willard's studies influenced public policy with her studies, which centered on plant life at high altitudes. Willard was responsible for the establishment of the Beatrice Willard Alpine Tundra Research Plots above the treeline in Rocky Mountain National Park, now listed on the National Register of Historic Places. In later years she was an adviser to U.S. presidents Nixon and Ford as the first woman on the Council on Environmental Quality (CEQ).
The High Sierra Camps are nine rustic lodging facilities located in two national parks and a national monument in California's Sierra Nevada mountain range. Open most years from June or July to September, they are staffed camps with tent cabins and food service facilities. The backcountry camps receive their supplies by pack mules.
Carlotta Case Hall was an American botanist and university professor who collected and published on ferns. She also co-authored a handbook on the plants of Yosemite National Park.
Clare Marie Hodges (1890–1970) was one of the first paid female rangers for the National Park Service, working at Yosemite National Park.
Mammoth Peak is a mountain in the area of Tuolumne Meadows, Yosemite National Park, California. The summit is a class 1-2 cross-country hike that features river crossings and boulder scrambling. The peak lies at the northern end of the Kuna Crest and is close to California State Route 120. From the road, its summit appears rounded and quite rocky. Though Mammoth Peak is not as popular as other nearby peaks, its relatively easily accessed summit affords tremendous views of Mount Gibbs, Mount Dana, and Mount Lewis.
