Mount Hood, also known as Wy'east, is an active stratovolcano in the Cascade Range and is a member of the Cascade Volcanic Arc. It was formed by a subduction zone on the Pacific Coast and rests in the Pacific Northwest region of the United States. It is located about {{cvt|50|mi|km}} east-southeast of Portland, on the border between Clackamas and Hood River counties, and forms part of the Mount Hood National Forest. Much of the mountain outside the ski areas is part of the Mount Hood Wilderness. With a summit elevation of 11,249 ft (3,429 m),{{cite ngs |id=RC2244 |designation=Mount Hood Highest Point |access-date=2008-03-31}} it is the highest mountain in the U.S. state of Oregon and is the fourth highest in the Cascade Range.{{cite web |url=http://vulcan.wr.usgs.gov/Volcanoes/PacificNW/AGU-T106/hood.html |author=Swanson, D.A. |year=1989 |work=Cenozoic Volcanism in the Cascade Range and Columbia Plateau, Southern Washington and Northernmost Oregon: AGU Field Trip Guidebook T106, July 3–8, 1989 |title=Mount Hood, Oregon |publisher=U.S. Geological Survey |access-date=2013-07-18 |display-authors=etal |archive-url=https://web.archive.org/web/19990203012926/http://vulcan.wr.usgs.gov/Volcanoes/PacificNW/AGU-T106/hood.html |archive-date=1999-02-03 |url-status=dead}} Ski areas on the mountain include Timberline Lodge ski area which offers the only year-round lift-served skiing in North America, Mount Hood Meadows, Mount Hood Skibowl, Summit Ski Area, and Cooper Spur ski area.

Naming

=Indigenous names=

It has been difficult to establish place names for Mount Hood that are of indigenous etymology, or to reconstruct names that may have been used prior to European contact.File:Mount Hood 2619s.jpg

== Wy'east ==

The name Wy'east has been associated with Mount Hood for more than a century, but no evidence suggests that it is a genuine name for the mountain in any indigenous language. The name was possibly inspired by an 1890 work of author Frederic Balch, although Balch does not use it himself.{{Cite news |newspaper=The Columbian |first=Andy |last=Matarrese |date=June 11, 2017 |url=https://www.columbian.com/news/2017/jun/11/anthropologist-dispelling-myths-with-plankhouse-talk/ |title=Anthropologist dispelling myths with plankhouse talk |access-date=2020-06-01 |archive-date=2020-10-05 |archive-url=https://web.archive.org/web/20201005105437/https://www.columbian.com/news/2017/jun/11/anthropologist-dispelling-myths-with-plankhouse-talk/ |url-status=live}}{{Cite journal |journal=Quartux |first=David G. |last=Lewis |url=https://ndnhistoryresearch.com/tribal-history-themes/native-place-names/ |title=Native Place Names |date=13 May 2018 |access-date=2020-06-01 |archive-date=2020-09-24 |archive-url=https://web.archive.org/web/20200924053735/https://ndnhistoryresearch.com/tribal-history-themes/native-place-names/ |url-status=live}}{{cite web |last1=Balch |first1=Frederic Homer |title=The Bridge of the Gods |url=https://archive.org/details/bridgeofgodsroma00balcuoft/page/x/mode/2up |website=Internet Archive |year=1890 |publisher=A.C.McClurg and Company |access-date=12 December 2020}} The name may have been popularized by his story being combined with a play around 1911 at Pacific College. It is also possible it was 'invented' by scholars in the 20th century or even a minister hearing it second-hand around the same time the play was happening.{{Cite web |title=Native Place Names – The Quartux Journal |url=https://ndnhistoryresearch.com/tribal-history-themes/native-place-names/ |access-date=2024-04-21 |website=ndnhistoryresearch.com|date=May 13, 2018 }}

In one version of Balch's story, the two sons of the Great Spirit Sahale fell in love with the beautiful maiden Loowit, who could not decide which to choose. The two braves, Wy'east and Pahto (unnamed in his novel, but appearing in a later adaptation), burned forests and villages in their battle over her. Sahale became enraged and smote the three lovers. Seeing what he had done, he erected three mountain peaks to mark where each fell. He made beautiful Mount St. Helens for Loowit, proud and erect Mount Hood for Wy'east, and the somber Mount Adams for the mourning Pahto.{{cite web |url=http://volcanoes.usgs.gov/observatories/cvo/Historical/naming_mount_adams.shtml |first=Lyn |last=Topinka |work=Volcanoes and History |publisher=Cascades Volcano Observatory (CVO) |date=2008-05-21 |title=Naming the Cascade Range Volcanoes: Mount Adams, Washington |access-date=2015-06-14 |archive-date=2015-04-03 |archive-url=https://web.archive.org/web/20150403055751/http://volcanoes.usgs.gov/observatories/cvo/Historical/naming_mount_adams.shtml |url-status=live}}

There are other versions of the legend. In another telling, Wy'east (Hood) battles Pahto (Adams) for the fair La-wa-la-clough (St. Helens). Or again Wy'east, the chief of the Multnomah tribe, competed with the chief of the Klickitat tribe. Their great anger led to their transformation into volcanoes. Their battle is said to have destroyed the Bridge of the Gods and thus created the great Cascades Rapids of the Columbia River.{{cite book |title=Indian Legends of the Pacific Northwest |url=https://archive.org/details/indianlegendsofp00clar |url-access=registration |last=Clark |first=Ella E. |publisher=University of California Press |location=Berkeley, California |year=1953 |isbn=0-520-23926-1 |oclc=51779712}}

== Other names ==

The mountain sits partly inside the reservation of the Confederated Tribes of Warm Springs, which comprises multiple languages including Sahaptin, Upper Chinook/Kiksht (Wasco) and Numu (Paiute). However, it has been difficult to determine names originating from these or other indigenous languages specifically referring to Mount Hood. Eugene Hunn suggests that the mountain may have lacked a specific name:{{Cite book |last=Hunn |first=Eugene |url=https://diglib.amphilsoc.org/islandora/object/hunn-eugene-plateau-indian-place-names |title=Plateau Indian Place Names |date=1988 |publisher=Phillips Fund for Native American Research Collection |pages=3 |language=English}}

Learning a landscape is not simply a matter of naming all the rivers and mountains... The Native American perspective emphasizes by contrast places as focal points of activity, places where significant human-landscape interactions occur. Thus, while a few prominent peaks may be given Indian names, such as taxùma [təqʷuʔməʔ] for Mt. Rainier (in the Puget Salish language) or lawilayt-łà [lawílatɬa], literally "the smoker," for Mt. St. Helens (in Sahaptin), other prominent peaks, e.g. Mts. Adams and Hood, are known simply as pàtu, a general term for snow-capped summit.

=Current name=

File:Northcote, Samuel Hood.jpg

The mountain was given its present name on October 29, 1792, by Lt. William Broughton, a member of Captain George Vancouver's exploration expedition. Lt. Broughton observed its peak while at Belle Vue Point of what is now called Sauvie Island during his travels up the Columbia River, writing, "A very high, snowy mountain now appeared rising beautifully conspicuous in the midst of an extensive tract of low or moderately elevated land [location of today's Vancouver, Washington] lying S 67 E., and seemed to announce a termination to the river." Lt. Broughton named the mountain after Samuel Hood, 1st Viscount Hood, a British admiral.

Lewis and Clark spotted the mountain on October 18, 1805. A few days later at what would become The Dalles, Clark wrote, "The pinnacle of the round topped mountain, which we saw a short distance below the banks of the river, is South 43-degrees West of us and about {{cvt|37|mi|km}}. It is at this time topped with snow. We called this the Falls Mountain, or Timm Mountain." Timm was the native name for Celilo Falls. Clark later noted that it was also Vancouver's Mount Hood.Grauer, p. 9{{cite web |url=http://vulcan.wr.usgs.gov/LivingWith/Historical/LewisClark/volcanoes_lewis_clark.html |title=The Volcanoes of Lewis and Clark – October 1805 to June 1806: Introduction |publisher=U.S. Geological Survey |first=Lyn |last=Topinka |date=2004-06-29 |access-date=2013-07-17 |archive-date=2013-02-24 |archive-url=https://web.archive.org/web/20130224231349/http://vulcan.wr.usgs.gov/LivingWith/Historical/LewisClark/volcanoes_lewis_clark.html |url-status=live}}

Two French explorers from the Hudson's Bay Company may have traveled into the Dog River area east of Mount Hood in 1818. They reported climbing to a glacier on "Montagne de Neige" (Mountain of Snow), probably Eliot Glacier.

Volcanic activity

File:Mount Hood, Oregon.jpg of Mount Hood]]

The glacially eroded summit area consists of several andesitic or dacitic lava domes; Pleistocene collapses produced avalanches and lahars (rapidly moving mudflows) that traveled across the Columbia River to the north. The eroded volcano has had at least four major eruptive periods during the past 15,000 years.{{cite web |url=http://volcanoes.usgs.gov/about/volcanoes/cascades/mounthood.php |title=Volcano Information: Mount Hood |publisher=U.S. Geological Survey |date=2008-06-02 |access-date=2013-07-18 |archive-date=2013-02-22 |archive-url=https://web.archive.org/web/20130222191000/http://volcanoes.usgs.gov/about/volcanoes/cascades/mounthood.php |url-status=live}}
{{PD-notice}}

The last three eruptions at Mount Hood occurred within the past 1,800 years from vents high on the southwest flank and produced deposits that were distributed primarily to the south and west along the Sandy and Zigzag rivers. The volcano has had a VEI of 2 at least three times before.{{cite web|url=https://volcano.si.edu/volcano.cfm?vn=322010|title=Global Volcanism Program | Hood|website=Smithsonian Institution | Global Volcanism Program|access-date=2024-09-18}} The last eruptive period took place around 220 to 170 years ago, when dacitic lava domes, pyroclastic flows and mudflows were produced without major explosive eruptions. The prominent Crater Rock just below the summit is hypothesized to be the remains of one of these now-eroded domes. This period includes the last major eruption of 1781 to 1782 with a slightly more recent episode ending shortly before the arrival of the explorers Lewis and Clark in 1805. The latest minor eruptive event was thought to have occurred in August 1907,{{cite journal |title=Recent Eruptive History of Mount Hood, Oregon, and Potential Hazards from Future Eruptions |first=Dwight R. |last=Crandell |journal=Geological Survey Bulletin |issue=1492 |url=https://pubs.er.usgs.gov/publication/b1492 |publisher=U.S. Geological Survey |year=1980 |pages=1, 7–8, 43–45 |doi=10.3133/b1492| access-date=2013-07-13| archive-date=2012-09-22| archive-url=https://web.archive.org/web/20120922065002/http://pubs.er.usgs.gov/publication/b1492| url-status=live|doi-access=free }} but has been discredited as "an observation of non-eruptive fumarolic activity."

The glaciers on the mountain's upper slopes may be a source of potentially dangerous lahars when the mountain next erupts. There are vents near the summit that are known for emitting gases such as carbon dioxide and sulfur dioxide.{{cite web |url=http://vulcan.wr.usgs.gov/Volcanoes/Hood/Publications/EV24-6/dome_collapse_hood.html |title=The Danger of Collapsing Lava Domes: Lessons for Mount Hood, Oregon |work=Earthquakes & Volcanoes, v. 24, n. 6, pp. 244–269 |first1=Steven R. |last1=Brantley |first2=William E. |last2=Scott |publisher=U.S. Geological Survey |access-date=2013-07-18 |archive-date=2013-06-22 |archive-url=https://web.archive.org/web/20130622132813/http://vulcan.wr.usgs.gov/Volcanoes/Hood/Publications/EV24-6/dome_collapse_hood.html |url-status=live}} Prior to the 1980 eruption of Mount St. Helens, the only known fatality related to volcanic activity in the Cascades occurred in 1934, when a climber suffocated in oxygen-poor air while exploring ice caves melted by fumaroles in Coalman Glacier on Mount Hood.

A conflict exists between protecting public safety and protecting the environment. In 2014, a USGS employee, Dr. Seth Moran, proposed installing new instruments on Mount Hood to warn of volcanic activity. The instruments were installed at four different locations on the mountain, including:

three seismometers to measure earthquakes
three Global Positioning System (GPS) instruments to measure ground movement
one instrument to measure gas emissions

The proposed locations were in a protected wilderness area, tightly controlled by the United States Forest Service. The project was opposed by Wilderness Watch, a conservation group.{{cite news |title=We're Barely Listening to the U.S.'s Most Dangerous Volcanoes—A thicket of red tape and regulations have made it difficult for volcanologists to build monitoring stations along Mount Hood and other active volcanoes. |author=Shannon Hall |date=September 9, 2019 |work=The New York Times |url=https://www.nytimes.com/2019/09/09/science/volcanoes-cascades-monitoring.html |access-date=January 2, 2023}}

Elevation

Mount Hood was first seen by European explorers in 1792 and is believed to have maintained a consistent summit elevation, varying by no more than a few feet due to mild seismic activity. Elevation changes since the 1950s are predominantly due to improved survey methods and model refinements of the shape of the Earth (see vertical reference datum). Despite the physical consistency, the estimated elevation of Mount Hood has varied substantially over the years, as seen in the following table:

Early explorers on the Columbia River estimated the elevation to be {{cvt|10000|to|12000|ft}}. Two people in Thomas J. Dryer's 1854 expedition calculated the elevation to be {{cvt|18361|ft}} and the tree line to be at {{cvt|11250|ft}}. Two months later, a Mr. Belden claimed to have climbed the mountain during a hunting trip and determined it to be {{cvt|19400|ft}} upon which "pores oozed blood, eyes bled, and blood rushed from their ears." Sometime by 1866, Reverend G. H. Atkinson determined it to be {{cvt|17600|ft}}. A Portland engineer used surveying methods from a Portland baseline and calculated a height of between {{cvt|18000|and|19000|ft}}. Many maps distributed in the late 19th century cited {{cvt|18361|ft}}, though Mitchell's School Atlas gave {{cvt|14000|ft}} as the correct value. For some time, many references assumed Mount Hood to be the highest point in North America.

Modern height surveys also vary, but not by the huge margins seen in the past. A 1993 survey by a scientific party that arrived at the peak's summit with {{cvt|16|lb|kg}} of electronic equipment reported a height of {{cvt|11240|ft|m|sigfig=4}}, claimed to be accurate to within {{cvt|1.25|in|mm}}.{{cite news |url=https://news.google.com/newspapers?nid=1310&dat=19930914&id=bm4VAAAAIBAJ&pg=1592,2999111 |title=How High is Hood |date=1993-09-14 |newspaper=The Register-Guard |location=Eugene, Oregon |format=editorial |page=A8 |access-date=2009-10-29 |archive-date=2021-01-31 |archive-url=https://web.archive.org/web/20210131052326/https://news.google.com/newspapers?nid=1310&dat=19930914&id=bm4VAAAAIBAJ&sjid=duoDAAAAIBAJ&pg=1592%2C2999111 |url-status=live}} Many modern sources likewise list {{cvt|11240|ft|m|sigfig=4}} as the height.{{cite book |last=Morris |first=Mark |title=Moon Oregon |publisher=Avalon Travel |year=2007 |edition=Seventh |page=107 |chapter=Columbia River Gorge and Mount Hood |isbn=978-1-56691-930-2|chapter-url=https://books.google.com/books?id=-xEA_1nkxcAC&pg=PA107 |location=Emeryville, California |oclc=74524856 |access-date=2009-10-29}}{{cite book |last1=Gutman |first1=Bill |first2=Shawn |last2=Frederick |title=Being Extreme: Thrills and Dangers in the World of High-risk Sports |publisher=Citadel Press |location=New York, New York |year=2003 |edition=Illustrated |page=234 |isbn=978-0-8065-2354-5 |url=https://books.google.com/books?id=YGKfVxFDXOUC&pg=PA234 |oclc=54525467 |access-date=2009-10-29}}{{cite book |last=Palmerlee |first=Danny |title=Pacific Northwest Trips |publisher=Lonely Planet |location=Oakland, California |oclc=244420587 |year=2009 |edition=Illustrated |page=[https://archive.org/details/lonelyplanetregi00palm/page/262 262] |isbn=978-1-74179-732-9 |url=https://archive.org/details/lonelyplanetregi00palm |url-access=registration |access-date=2009-10-29}} However, numerous others place the peak's height one foot lower, at {{cvt|11239|ft|m}}.{{cite book |last=Helman |first=Adam |title=The Finest Peaks: Prominence and Other Mountain Measures |publisher=Trafford Publishing |location=Victoria, British Columbia |year=2005 |page=114 |chapter=Table of United States Peaks by Spire Measure |isbn=9781412059947 |oclc=71147989|chapter-url=https://books.google.com/books?id=Dl9tJFsvYvYC&pg=PA114}}{{cite book |last1=Marbach |first1=Peter |last2=Cook |first2=Janet |title=Mount Hood: The Heart of Oregon |publisher=Graphic Arts Center Publishing |location=Portland, Oregon |year=2005 |edition=Illustrated |page=18 |isbn=978-1-55868-923-7 |oclc=60839414 |url=https://books.google.com/books?id=MdB0mpVvktAC&pg=PA18 |access-date=2009-10-29 |archive-date=2017-02-07 |archive-url=https://web.archive.org/web/20170207094227/https://books.google.com/books?id=MdB0mpVvktAC&pg=PA18 |url-status=live}}{{cite journal |last=DeBenedetti |first=Christian |date=March 2005 |title=Cliff Hanger |journal=Popular Mechanics |publisher=Hearst Magazines |volume=182 |issue=3 |page=136 |issn=0032-4558 |url=https://books.google.com/books?id=Vc8DAAAAMBAJ&pg=PA136 |access-date=2009-10-29 |archive-date=2017-02-07 |archive-url=https://web.archive.org/web/20170207175421/https://books.google.com/books?id=Vc8DAAAAMBAJ&pg=PA136 |url-status=live}} Finally, a height of {{cvt|11249|ft|m}} has also been reported.{{cite book |last=Bernstein |first=Art |title=Oregon Byways: 75 Scenic Drives in the Cascades and Siskiyous, Canyons and Coast |publisher=Wilderness Press |location=Berkeley, California |year=2003 |page=[https://archive.org/details/oregonbywaystony00artb/page/12 12] |oclc=53021936 |isbn=978-0-89997-277-0 |url=https://archive.org/details/oregonbywaystony00artb |url-access=registration |access-date=2009-10-29}}{{cite book |series=Let's Go |title=Roadtripping USA: The Complete Coast-to-Coast Guide to America |publisher=St. Martin's Press |location=New York, New York |year=2009 |edition=Third |page=340 |isbn=978-0-312-38583-5 |oclc=243544813 |url=https://books.google.com/books?id=69z1qsLK_qkC&pg=PA340 |access-date=2009-10-29 |archive-date=2014-06-28 |archive-url=https://web.archive.org/web/20140628025452/http://books.google.com/books?id=69z1qsLK_qkC&pg=PA340 |url-status=live}}{{cite news |url=http://www.climbing.com/news/climbers-stranded-on-mount-hood/ |title=Climbers Stranded on Mount Hood |last=Pluth |first=Tanya |year=2009 |publisher=climbing.com (Skram Media) |archive-url=https://web.archive.org/web/20140308195505/http://www.climbing.com/news/climbers-stranded-on-mount-hood/ |archive-date=2014-03-08}}

The glaciers and permanent snow fields have an area of {{cvt|3331|acre|ha}} and contain a volume of about {{cvt|282000|acre.ft|km3}}. Eliot Glacier is the largest glacier by volume at {{cvt|73000|acre.ft|km3|2}}, and has the thickest depth measured by ice radar at {{cvt|361|ft|m}}. The largest glacier by surface area is the Coe-Ladd Glacier system at {{cvt|531|acres|ha}}.

Glaciers and snowfields cover about 80 percent of the mountain above the {{cvt|6900|ft|m|adj=on}} level. The glaciers declined by an average of 34 percent from 1907 to 2004. Glaciers on Mount Hood retreated through the first half of the 20th century, advanced or at least slowed their retreat in the 1960s and 1970s, and have since returned to a pattern of retreat.{{cite journal |last1=Jackson |first1=Keith M. |last2=Fountain |first2=Andrew G. |year=2007 |title=Spatial and morphologic change on Eliot Glacier, Mount Hood, Oregon, USA |journal=Annals of Glaciology |volume=46 |issue=1 |pages=222–226 |bibcode=2007AnGla..46..222J |doi=10.3189/172756407782871152 |doi-access=free}} The neo-glacial maximum extents formed in the early 18th century.

During the last major glacial event between 29,000 and 10,000 years ago, glaciers reached down to the {{cvt|2600|to|2300|ft|m|adj=on}} level, a distance of {{cvt|9.3|mi|km}} from the summit. The retreat released considerable outwash, some of which filled and flattened the upper Hood River Valley near Parkdale and formed Dee Flat.

Older glaciation produced moraines near Brightwood and distinctive cuts on the southeast side; they may date to 140,000 years ago.

Hiking

File:Portland, Vancouver, and Mount Hood.jpg

Mt. Hood National Forest is home to approximately {{cvt|1,000|mi|km}} of trails.{{Cite web |title=Mt Hood National Forest |url=https://www.fs.usda.gov/activity/mthood/recreation/hiking |website=USDA Forest Service}} Cooper Spur Trail leads to {{cvt|8,510|ft|m}} in elevation, the highest reachable point one can gain on the mountain without requiring mountaineering gear.

The Timberline Trail, which circumnavigates the entire mountain and rises as high as {{cvt|7,300|ft|m}}, was built in the 1930s by the Civilian Conservation Corps. Typically, the {{cvt|40.7|mi|km|adj=on}} hike is snow-free from late July until the autumn snows begin. The trail includes over {{cvt|10,000|ft|m}} of elevation gain and loss and can vary in distance year to year depending on river crossings. There are many access points, the shortest being a small walk from the Timberline Lodge. A portion of the Pacific Crest Trail is coincident with the Timberline Trail on the west side of Mount Hood.{{cite web |url=http://www.fs.usda.gov/recarea/mthood/recarea/?recid=53506 |title=Timberline National Historic Trail #600 |publisher=U.S. Forest Service |access-date=2013-09-15 |archive-date=2015-01-03 |archive-url=https://web.archive.org/web/20150103035648/http://www.fs.usda.gov/recarea/mthood/recarea/?recid=53506 |url-status=live}}{{cite web |url=http://www.gorp.com/parks-guide/travel-ta-mount-hood-wilderness-area-portland-hiking-sidwcmdev_054748.html |title=Weekend Backpacker: Portland |page=2 |first=Greg |last=Cook |publisher=GORP |access-date=2013-09-15 |archive-url=https://web.archive.org/web/20140728090836/http://www.gorp.com/parks-guide/travel-ta-mount-hood-wilderness-area-portland-hiking-sidwcmdev_054748.html |archive-date=2014-07-28 |url-status=dead}}

About 10,000 people attempt to climb Mount Hood each year.{{cite news |url=http://blog.oregonlive.com/breakingnews/2007/02/everything_goes_right_in_mount.html |title=Everything goes right in Mount Hood search |last1=Green |first1=Aimee |last2=Larabee |first2=Mark |last3=Muldoon |first3=Katy |newspaper=The Oregonian |location=Portland, Oregon |date=2007-02-19 |archive-url=https://web.archive.org/web/20071223093250/http://blog.oregonlive.com/breakingnews/2007/02/everything_goes_right_in_mount.html |archive-date=2007-12-23 |access-date=2008-12-19}} It has convenient access, though it presents some technical climbing challenges. There are no trails to the summit, with even the "easier" southside climbing route constituting a technical climb with crevasses, falling rocks, and often inclement weather. Ropes, ice axes, crampons and other technical mountaineering gear are necessary.{{Cite news |url=https://gethighonaltitude.com/2019/01/15/mt-hood-pearly-gates-winter-ascent/ |title="Mount Hood Pearly Gates" GetHighOnAltitude.com |newspaper=Get High on Altitude |date=16 January 2019 |access-date=2019-04-12 |archive-date=2019-04-12 |archive-url=https://web.archive.org/web/20190412175816/https://gethighonaltitude.com/2019/01/15/mt-hood-pearly-gates-winter-ascent/ |url-status=live}} Peak climbing season is generally from April to mid-June.{{cite web |url=http://www.fs.usda.gov/recarea/mthood/recarea/?recid=80001 |title=Mount Hood Summit |publisher=USDA Forest Service |access-date=2014-02-18 |archive-date=2014-02-27 |archive-url=https://web.archive.org/web/20140227111701/http://www.fs.usda.gov/recarea/mthood/recarea/?recid=80001 |url-status=live}}

There are six main routes to approach the mountain, with about 30 total variations for summiting. The climbs range in difficulty from class 2 to class 5.9+ (for Acrophobia).{{cite web |url=http://www.summitpost.org/mount-hood/150189#chapter_2 |title=Mount Hood |publisher=SummitPost |date=2010-06-09 |access-date=2011-11-27 |archive-date=2012-11-07 |archive-url=https://web.archive.org/web/20121107084951/http://www.summitpost.org/mount-hood/150189#chapter_2 |url-status=live}} The most popular route, dubbed the south route, begins at Timberline Lodge and proceeds up Palmer Glacier to Crater Rock, the large prominence at the head of the glacier. The route goes east around Crater Rock and crosses the Coalman Glacier on the Hogsback, a ridge spanning from Crater Rock to the approach to the summit. The Hogsback terminates at a bergschrund where the Coalman Glacier separates from the summit rock headwall. The route continues to the Pearly Gates, a gap in the summit rock formation, then right onto the summit plateau and the summit proper.{{cite web |url=http://www.trimbleoutdoors.com/ViewTrip/54445 |title=Portland, OR: Mount Hood via the South Side Route |work=Backpacker Magazine |publisher=Trimble Outdoors |date=2008-05-12 |access-date=2011-11-27 |archive-date=2012-04-06 |archive-url=https://web.archive.org/web/20120406172352/http://www.trimbleoutdoors.com/ViewTrip/54445 |url-status=live}}

Technical ice axes, fall protection, and experience are now recommended in order to attempt the left chute variation or Pearly Gates ice chute. The Forest Service recommends several other route options due to these changes in conditions (e.g. "Old Chute," West Crater Rim, etc.).{{cite web |url=http://www.fs.fed.us/r6/mthood/recreation/climbing/conditions.shtml |title=Climbing Mount Hood: Southside Climbing Conditions – June 9, 2007 |publisher=United States Forest Service |archive-url=https://web.archive.org/web/20070614102410/http://www.fs.fed.us/r6/mthood/recreation/climbing/conditions.shtml |archive-date=2007-06-14}}

As of May 2002, more than 130 people had died in climbing-related accidents since records have been kept on Mount Hood, the first in 1896.{{cite web |url=http://www.cbsnews.com/news/last-body-recovered-from-mt-hood/ |title=Last Body Recovered From Mount Hood |author=Holguin, Jaime |publisher=CBS News |date=2002-05-30 |access-date=2014-03-09 |archive-date=2014-03-10 |archive-url=https://web.archive.org/web/20140310073234/http://www.cbsnews.com/news/last-body-recovered-from-mt-hood/ |url-status=live}} Incidents in May 1986, December 2006, and December 2009 attracted intense national and international media interest. Though avalanches are a common hazard on other glaciated mountains, most Mount Hood climbing deaths are the result of falls and hypothermia.{{Cite web |url=http://www.gorp.com/parks-guide/travel-ta-mount-hood-national-forest-oregon-sidwcmdev_066522.html |title=Mount Hood National Forest Technical Climbing |publisher=GORP.com |access-date=2008-08-28 |archive-url=https://web.archive.org/web/20100513021549/http://www.gorp.com/parks-guide/travel-ta-mount-hood-national-forest-oregon-sidwcmdev_066522.html |archive-date=2010-05-13 |url-status=dead}}
