Harlequin Dome is a granite dome, quite near Tenaya Lake, in the Tuolumne Meadows region of Yosemite National Park. Finding Harlequin Dome From the parking lot at Tenaya Lake, cross Highway 120, hike up slabs to a short headwall. Continue up the trail to the base of the cliff. Harlequin Dome is directly across from Pywiack Dome.

It has one-to-three pitch climbs, but the climbs wander a bit, and the approach is easier.

Almost 95 percent of the park is designated National Wilderness Preservation System, wilderness.

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Sierra Nevada (U
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 north-south and its width ranges from to 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 , 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, and Kings Canyon National Parks; and Devils ...

Granite Dome
Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the Earth's surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to Earth's surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in onionlike patterns that are parallel to the land surface. These sheets of rock peel off the exposed surface and in certain conditions develop domical structures. Additional theories on the origin of granite domes involve scarp-retreat and tectonic uplift. Sheet fractures Sheet fractures are arcuate fractures defining slabs of rock that range from 0.5 to 10 meters thic ... [...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] |
California State Route 120
State Route 120 (SR 120) is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season. Route description SR 120 begins as a freeway intersecting Interstate 5 to extend Interstate 205 through Manteca. In east Manteca the freeway ends at SR 99 and becomes a highway which continues to head east through Escalon, Oakdale and other various small towns. East of Oakdale there are no highly populated area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pywiack Dome
Pywiack Dome is a prominent 600 foot granite dome in Yosemite National Park, located north-east of Tenaya Lake, west of Tuolumne Meadows and from the Tioga Road. It is quite near Harlequin Dome, and North and South Whizz Domes are north. Josiah Whitney the head of California Geological Survey wrote in 1863 about Pywiack Dome in ''Geology'': Climbing The west face of the formation is popular with rock climbers and has several multi-pitch slab climbs easily visible from the Tioga Road. Earliest was ''Dike Route'' a 6 pitch YDS 5.9R first climbed in August 1966 by Tom Gerughty, Roger Evje and Dave Meeks. Other popular climbs include Zee Tree (a 5 pitch YDS 5.7) and Aqua Knobby (a 4 pitch YDS 5.9) Etymology "Py-we-ack" in the native language means "glistening rocks", and the native people applied it to both the Tenaya Creek and Tenaya Lake, due to the abundance of glacial polish in the upper Tenaya basin. In 1932 the name "Pywiack" has applied to Pywiack Cascade. Pyw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jim Bridwell
Jim Bridwell (July 29, 1944 – February 16, 2018) was an American rock climber and mountaineer, active since 1965, especially in Yosemite Valley, but also in Patagonia and Alaska. He was noted for pushing the standards of both free climbing and big-wall climbing, and later alpine climbing. He wrote numerous articles on climbing for leading sport publications. He was an apprentice to Royal Robbins and Warren Harding (climber). He was the unofficial leader of the Stonemasters. Bridwell is credited with over 100 First Ascents in Yosemite Valley, in addition to conducting the first one-day ascent of The Nose of El Capitan on May 26, 1975 with John Long and Billy Westbay. He founded Yosemite National Park's Search and Rescue Team (YOSAR), and spearheaded many rescues that became textbook for search-and-rescue operations. He was a leading force in the changing techniques of climbing and an innovator/inventor of widely used and copied climbing gear, including copperheads and ...

Pitch (ascent/descent)
In rock climbing and ice climbing, a pitch is a steep section of a route that requires a rope between two belays, as part of a climbing system. Standard climbing ropes are between 50 and 80 metres long, so a pitch is always shorter, between two convenient ledges if possible; longer routes are multi-pitch, requiring the re-use of the rope each time. In free climbing, pitch refers to classification by climbers of the difficulty of ascent on certain climbing routes. illustrated superimposed on the successful ascent of the Dawn Wall, as photographed on El Capitan in Yosemite. In climbing In advanced climbing or mountaineering, another definition of ''pitch'' is not restricted by the length of the rope.
