'''Half Dome''' is a [[quartz monzonite]] [[batholith]] at the eastern end of [[Yosemite Valley]] in [[Yosemite National Park]], California. It is a well-known [[List of rock formations|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.<ref>{{Cite web|title = USGS FAQs - Recreation - Half Dome, the massive rock monument in Yosemite National Park|url = http://www.usgs.gov/faq/categories/9758/3243%2520|website = www.usgs.gov|access-date = 2016-02-11|archive-url = https://web.archive.org/web/20160215105445/http://www.usgs.gov/faq/categories/9758/3243%20|archive-date = 2016-02-15|url-status = dead}}</ref>

==Geology==
{{main|Geology of the Yosemite area}}
[[File:Half Dome10.jpg|thumb|left|Half Dome seen from Washburn Point]]
The impression from the valley floor that this is a round dome that has lost its northwest half, is just an illusion. From Washburn Point, Half Dome can be seen as a thin ridge of rock, an [[arête]], that is oriented northeast–southwest, with its southeast side almost as steep as its northwest side except for the very top. Although the trend of this ridge, as well as that of [[Tenaya Canyon]], is probably controlled by master [[Joint (geology)|joints]], 80 percent of the northwest "half" of the original dome may well still be there.

==Ascents==
[[File:Rainbow at Half Dome.jpg|thumb|left|A [[rainbow]] over Half Dome]]
As late as the 1870s, Half Dome was described as "perfectly inaccessible" by [[Josiah Whitney]] of the [[California Geological Survey]].<ref>{{cite book |last=Jones |first=Chris |title=Climbing in North America |publisher=American Alpine Club / University of California Press |year=1976 |location=Berkeley, California |page=[https://archive.org/details/climbinginnortha0000jone/page/26 26] |isbn=0-520-02976-3 |url=https://archive.org/details/climbinginnortha0000jone/page/26 }}</ref> The summit was reached by [[George Anderson (mountaineer)|George Anderson]] in October 1875, via a route constructed by drilling and placing iron eye bolts into the smooth rock.<ref name="Jones 27">{{cite book |last=Jones |first=Chris |title=Climbing in North America |date=January 1976 |page=[https://archive.org/details/climbinginnortha0000jone/page/27 27] |publisher=University of California Press |isbn=0-520-02976-3 |url=https://archive.org/details/climbinginnortha0000jone/page/27 }}</ref>  Anderson had previously tried a variety of methods, including using pitch from nearby pine trees for extra friction.<ref name=heart_sierra>{{cite book |last=Hutchings |first=James Mason |authorlink=James Mason Hutchings |title=In the heart of the Sierras |url=https://archive.org/details/inheartofsierras00hutc_0/ |accessdate=September 25, 2022 |year=1888 |publisher= |location= |isbn= |pages=458–459 }}</ref>

Anderson subsequently went on to add ropes to his eye bolts, so that other people could climb. Among those who took advantage was the first woman to climb Half Dome in 1876, S. L. Dutcher, of San Francisco. In 1877 [[James Mason Hutchings]] along with Anderson led a climb which included Hutchings' daughter Cosie, his son Willie, his mother-in-law Florence Sproat, aged 65, and two other women.<ref name=heart_sierra /><ref>{{cite book |last=Huntley |first=Jen A |authorlink= |title=The Making of Yosemite: James Mason Hutchings and the Origin of America's Most Popular National Park |url= |accessdate= |year=2011 |publisher= University Press of Kansas|location= |isbn=978-0-7006-1805-7 |page=160 }}</ref>

Today, Half Dome may be ascended in several different ways. Thousands of [[hiking|hiker]]s reach the top each year by following an {{convert|8.5|mi|km|1|abbr=on}} trail from the valley floor. After a rigorous {{convert|2|mi|km|1|abbr=on}} approach, including several hundred feet of rock stairs, the final pitch up the peak's steep but somewhat rounded east face is ascended with the aid of a pair of post-mounted steel cables originally constructed close to the Anderson route in 1919.

Alternatively, over a dozen [[rock climbing]] [[climbing route|route]]s lead from the valley up Half Dome's vertical northwest face. The first technical ascent was in 1957 via a route pioneered by [[Royal Robbins]], Mike Sherrick, and Jerry Gallwas, today known as the [[Regular Northwest Face of Half Dome|Regular Northwest Face]]. Their five-day epic was the first [[grade (climbing)|Grade VI]] climb in the United States.<ref>{{cite book |last=Jones |first=Chris |title=Climbing in North America |date=January 1976 |pages=[https://archive.org/details/climbinginnortha0000jone/page/207 207–211] |publisher=University of California Press |isbn=0-520-02976-3 |url=https://archive.org/details/climbinginnortha0000jone/page/207 }}</ref> Their route has now been [[free climb]]ed several times in a few hours' time. Other technical routes ascend the south face and the west shoulder.

==Hiking the Cable Route==
[[Image:Half Dome--cables.jpeg|thumb|Hikers use cables to ascend Half Dome]]
The Half Dome Cable Route hike runs from the valley floor to the top of the dome in {{convert|8.2|mi|km|0|abbr=on}} (via the Mist Trail), with {{convert|4800|ft|m|-1|abbr=on}} of elevation gain. The length and difficulty of the trail used to keep it less crowded than other park trails, but trail traffic grew to as many as 1,000 people a day, and about 50,000 per year, before a permit system was introduced in 2010.<ref name="merc">{{cite news|title=Death of Sunnyvale hiker on Half Dome called unusual|author-last1=Skipitares|author-first1=Connie|work=San Jose Mercury News|date=2007-06-19|url=http://www.mercurynews.com/ci_6180679?source=most_emailed}}</ref><ref name="MSNBC">{{cite web | url = https://www.nbcnews.com/id/wbna31348114 | title = Hiker falls to death from Yosemite's Half Dome | website = [[NBC News]] | date = 14 June 2009 }}</ref><ref name="hdpermits2010">{{cite web|url=http://www.nps.gov/yose/planyourvisit/hdpermits.htm|work=Yosemite National Park|title=Half Dome Permits|publisher=U.S. National Park Service|date=2010-01-31|archive-date=2010-02-02|archive-url=https://web.archive.org/web/20100202062129/http://www.nps.gov/yose/planyourvisit/hdpermits.htm|url-status=dead}}</ref> The hike can be done from the valley floor in a single long day, but many people break it up by camping overnight in [[Little Yosemite Valley]]. The trail climbs past [[Vernal Fall]] and [[Nevada Fall]], then continues into Little Yosemite Valley, then north to the base of the northeast ridge of Half Dome itself.

The final {{convert|400|ft|m|-1|abbr=on}} ascent is steeply up the rock between two steel cables used as handholds.<ref name="NPS cable route">{{cite web|title=Half Dome Day Hike|url=http://www.nps.gov/yose/planyourvisit/halfdome.htm|work=Yosemite National Park|publisher=National Park Service|access-date=2007-08-12}}</ref> The cables are fixed with bolts in the rock and raised onto a series of metal poles in late May. The poles do not anchor the cables. The cables are taken down from the poles for the winter in early October, but they are still fixed to the rock surface and can be used. The National Park Service recommends against climbing the route when the cables are down, or when the surface of the rock is wet and slippery.<ref name="NPS cable route"/> The ''Cable Route'' is rated [[Grade (climbing)#Yosemite Decimal System|class 3]], while the same face away from the cables is rated class 5.<ref>{{cite book|last=Secor|first=R.J.|title=The High Sierra: Peaks, Passes, and Trails|year=1999|edition=2nd|publisher=The Mountaineers|page=391|isbn=0-89886-313-9}}</ref>

[[Image:HalfDomeTraffic.jpeg|thumb|upright|The ''Cable Route'' gets crowded on the weekends]]
The Cable Route can be crowded. Since 2010, all hikers who intend to ascend the Cable Route must first obtain permits when the cables are up between May and October.<ref name="hdpermits">{{cite web|url=http://www.nps.gov/yose/planyourvisit/hdpermits.htm|title=Yosemite National Park: Half Dome Permits|publisher=National Park Service|access-date=2011-08-20}}</ref> Permits are limited to 300 per day, and {{as of|2022|lc=y}}, more than 70,000 applications were received in the pre-season and daily permit lotteries.<ref>{{cite web |title=Half Dome Permit Lottery Statistics - Yosemite National Park (U.S. National Park Service) |url=https://www.nps.gov/yose/planyourvisit/hdpermitsapps.htm |website=www.nps.gov |publisher=U.S. National Park Service |access-date=15 November 2023 |language=en |date=9 June 2023}}</ref> Permits are checked by a ranger on the trail. Hikers without permits are not allowed to hike beyond the base of the sub-dome or to the bottom of the cables. Hikers caught bypassing the rangers to visit either the sub-dome or main dome without a permit face fines of up to $5,000, and/or 6 months in jail.<ref>{{cite news|url=http://latimesblogs.latimes.com/outposts/2010/02/yosemite-half-dome-permits.html|title=Yosemite will require permits for Half Dome hikes, starting in May|newspaper=LA Times|access-date=14 December 2010|date=February 1, 2010|url-status=dead|archive-url=https://web.archive.org/web/20100329100701/http://latimesblogs.latimes.com/outposts/2010/02/yosemite-half-dome-permits.html|archive-date=29 March 2010}}</ref>

Backpackers with an appropriate wilderness permit can receive a Half Dome permit when they pick up their wilderness permit with no additional reservation required. Rock climbers who reach the top of Half Dome without entering the subdome area can descend on the Half Dome Trail without a permit.<ref name=hdpermits/>

The top of Half Dome is a large, flat area where climbers can relax and enjoy their accomplishment. The summit offers views of the surrounding areas, including Little Yosemite Valley and the Valley Floor. A notable location to one side of Half Dome is the "Diving Board", where [[Ansel Adams]] took his photograph ''[[Monolith, the Face of Half Dome]]'' on April 10, 1927. Often confused with "the Visor," a small overhanging ledge at the summit, the Diving Board is on the shoulder of Half Dome.<ref>{{cite web | url = http://www.nps.gov/yose/historyculture/ansel-adams.htm | title = NPS: Ansel Adams in Yosemite National Park }}</ref>

The Cable Route was added to the [[National Register of Historic Places]] in 2012.<ref>{{cite web |date=September 7, 2012 |title=Weekly List of Actions Taken on Properties: 8/27/12 Through 8/31/12 |url=http://www.nps.gov/history/nr/listings/20120907.htm |access-date=September 19, 2013 |publisher=[[National Park Service]]}}</ref>

Half Dome was originally called "''Tis-sa-ack''", meaning Cleft Rock in the language of the local [[Ahwahnechee people]]. Tis-sa-ack is also the name of the fourth route on the formation, ascended by [[Royal Robbins]] and Don Peterson over eight days in October 1969. Tis-sa-ack is the name of a mother from a native legend.

Half Dome was used as the logo for a software company, [[Sierra On-Line]].

In 1971, [[outdoor recreation]] and climbing equipment company [[The North Face]] created their company [[logo]], based upon a stylized depiction of the Half Dome formation.
