'''Longs Peak''' is a [[mountain]] in the northern [[Front Range]] of the [[Rocky Mountains]] of North America. The {{convert|4345.22|m|0|order=flip|comma=5|adj=on}} [[fourteener]] is located in the [[Rocky Mountain National Park Wilderness]], {{convert|15.5|km|order=flip}} southwest by south ([[Absolute bearing|bearing]] 209°) of the [[Estes Park, Colorado|Town of Estes Park]], [[Colorado]], [[United States]]. Longs Peak is the northernmost fourteener in the Rocky Mountains and the [[List of Colorado county high points|highest point]] in [[Boulder County, CO|Boulder County]] and [[Rocky Mountain National Park]].  The mountain was named in honor of explorer [[Stephen Harriman Long]] and is featured on the Colorado state quarter.<ref name=NGS/><ref name=PB/><ref name=GNIS/>{{efn|name=NAVD88|The elevation of Longs Peak includes an adjustment of +1.652&nbsp;m (+5.42&nbsp;ft) from [[Sea Level Datum of 1929|NGVD&nbsp;29]] to [[North American Vertical Datum of 1988|NAVD&nbsp;88]].}}<ref>{{cite book|last=Dziezynski|first=James|title=Best Summit Hikes in Colorado: An Opinionated Guide to 50+ Ascents of Classic and Little-Known Peaks from 8,144 to 14,433 Feet|url=https://books.google.com/books?id=KT0Uf6MLtisC&pg=PA98|date=1 August 2012|publisher=Wilderness Press|isbn=978-0-89997-713-3|page=98}}</ref><ref>{{Cite web |date=2020-07-24 |title=Colorado Places: Their Native American Names |url=https://www.colorado.edu/cnais/resources/colorado-places-their-native-american-names |access-date=2024-01-12 |website=Center for Native American and Indigenous Studies (CNAIS) |language=en}}</ref>

[[File:Trail Ridge Road and Longs Peak by RO.jpg|thumb|290px|Longs Peak (left of center), Pagoda Peak (center, in sun), [[Chiefs Head Peak|Chiefs Head]] (right of center, in shadow), and [[Terra Tomah Mountain]] (at far right edge, in shadow), from {{convert|12000|feet}} above sea level in [[Rocky Mountain National Park]]]]
Longs Peak can be seen behind [[Mount Meeker|Mt. Meeker]] from [[Longmont, Colorado]] and more directly from [[Loveland, Colorado]], as well as from most of the northern [[Front Range Urban Corridor]]. It is one of the most prominent mountains in Colorado, rising {{convert|9000|ft}} above the western edge of the [[Great Plains]].

The peak is named for Major [[Stephen Harriman Long]],<ref>{{cite web|last1=Jessen|first1=Kenneth|title=Colorado History: William Byers among first white men to climb Longs Peak|url=http://www.reporterherald.com/columnists/colorado-history/ci_27414881/colorado-history-william-byers-among-first-white-men|website=Reporter Herald|date=29 January 2015 |publisher=Loveland Reporter Herald}}</ref><ref name="GuideTo14" /> who is said to have been the first to spot the Front Range on June 30, 1820, during an [[Long's Expedition of 1820|expedition on behalf of the U.S. government]].

Together with nearby [[Mount Meeker]], with an elevation of 13,911 feet, the two mountains are sometimes referred to as the '''Twin Peaks''' (not to be confused with a nearby lower mountain called [[Twin Sisters Peaks|Twin Sisters]]).

==History of ascents==
As the only [[List of Colorado fourteeners|fourteener]] in [[Rocky Mountain National Park]], the peak has long been of interest to [[climbing|climbers]].  The easiest route is not "technical" during the summer season. It was probably first used by [[Pre-Columbian era|pre-Columbian]] [[Native Americans in the United States|indigenous people]] collecting [[eagle]] feathers.

The first recorded ascent was on August 23, 1868 by the surveying party of [[John Wesley Powell]] via the south side.<ref name="GuideTo14" />  Addie Alexander was the first woman to summit Longs Peak in 1871.<ref>{{Cite book|url=https://archive.org/details/magnificentmount00jane_0|title=The magnificent mountain women : adventures in the Colorado Rockies|last=Robertson, Janet, 1935-|date=1990|publisher=University of Nebraska Press|isbn=0803238924|location=Lincoln|oclc=19847483|url-access=registration}}</ref> Isabella L Bird also recounts an ascent in the 1870s in one of her letters (A Lady’s Life in the Rocky Mountains)

The East Face of the mountain is 1,675 feet, steep, and surmounted by a 1,000 feet steep sheer cliff known as "[[The Diamond (Longs Peak)|The Diamond]]"<ref name="GuideTo14">{{cite book|title=A Climbing Guide To Colorado's Fourteeners|edition=2|author1=Walter R. Borneman|author2=Lyndon J. Lampert|year=1989|page=[https://archive.org/details/climbingguidetoc00born/page/24 24]|isbn=0871087510|url=https://archive.org/details/climbingguidetoc00born/page/24}}</ref> (so-named because of its shape, approximately that of a cut [[diamond]] seen from the side and inverted). Another famous profile belongs to Longs Peak: to the southeast of the summit is a series of rises which, when viewed from the northeast, resembles a [[beaver]]. Lumena Wortman Buhl was the first woman to summit the east face of the mountain.(https://en.wikipedia.org/wiki/Carl_Blaurock)

In 1954 the first proposal made to the [[National Park Service]] to climb [[The Diamond (Longs Peak)|The Diamond]] was met with an official closure, a stance not changed until 1960.  The Diamond was first ascended by [[Dave Rearick]] and [[Bob Kamps]] that year, by a route that would come to be known simply as [[D1 (Longs Peak)|D1]].  This route would later be listed in Allen Steck and Steve Roper's influential book ''[[Fifty Classic Climbs of North America]]''.<ref>{{Fifty Classic Climbs}}</ref><ref>{{cite book|title=Climb!: The History of Rock Climbing in Colorado |author1=Jeff Achey |author2=Dudley Chelton |author3=Bob Godfrey |publisher=The Mountaineers Books |year=2002 |isbn=0-89886-876-9}}</ref>  The easiest route on the face is the [[Casual Route (Longs Peak)|Casual Route]] (5.10a),<ref>{{cite web |url=http://www.mountainproject.com/v/colorado/alpine_rock/rmnp__rock/105748496 |title=Casual Route |publisher=Mountain Project}}</ref> first climbed in 1977. It has since become the most popular route up the wall.

Clark's Arrow (4th-class) is a climb to the summit of Longs named after John Michael Clark, who was a park ranger in Rocky Mountain National Park in the 1950s.<ref>{{cite web | url=http://boulderdailycamera.co.newsmemory.com/?selDate=20201218&goTo=B02&artid=1 | title=Boulder Daily Camera }}</ref> The oldest person to summit Longs Peak was Rev. William "Col. Billy" Butler, who climbed it on September 2, 1926, his 85th birthday. In 1932, Clerin "Zumie" Zumwalt summited Longs Peak 53 times.<ref>{{Cite web|url=https://www.nps.gov/romo/planyourvisit/essentials.htm|title=Hiking Essentials - Rocky Mountain National Park (U.S. National Park Service)|first1=Mailing Address: 1000 US Hwy 36 Estes|last1=Park|first2=CO 80517 Phone: 970 586-1206 The Information Office is open year-round: 8:00 a m- 4:00 p m daily in summer; 8:00 a m- 4:00 p m Mondays-|last2=Fridays|first3=8:00 a m-12:00 p m Saturdays- Sundays in winter Recorded Trail Ridge Road status:586-1222 Contact|last3=Us|website=www.nps.gov}}</ref>

The record number of ascents to the summit of Longs Peak is 428, by [[Jim Detterline]]. Jim was a rescue Ranger in Rocky Mountain National Park. On October 23, 2016, he died in an accident while solo climbing.
Jim rescued over 1,000 people in the mountains of Rocky Mountain National Park and he received the U.S. Interior Department's Valor Award. He also earned the title "Mr. Longs Peak".<ref>{{Cite web|url=http://www.alpinist.com/doc/web16f/newswire-detterline-obit|title=Jim Detterline touched many lives as a climbing ranger in Rocky Mountain Nat'l Park - Alpinist.com|website=www.alpinist.com}}</ref>

On June 6, 2016, a group of US Special Forces were rescued after members of the team suffered from altitude sickness.<ref>{{Cite web|url=https://www.nbcnews.com/news/us-news/military-personnel-rescued-colorado-s-14-000-foot-longs-peak-n585496|title=Special Forces Rescued From Colorado's 14,000-Foot Longs Peak|website=NBC News}}</ref>

== Mills Glacier ==
Longs Peak has one remaining glacier named [[Mills Glacier]]. The glacier is located around 12,800 feet (3,900 m)<ref>{{Cite web|url=https://www.topoquest.com/map.php?lat=40.25556&lon=-105.60972&datum=nad27&zoom=4|title=Mills Glacier, CO - N40.25556° W105.60972°|website=www.topoquest.com}}</ref> at the base of the Eastern Face, just above Chasm Lake. A permanent snowfield, called [[The Dove (glacier)|The Dove]], is located north of Longs Peak.

==Climbing Longs Peak==
[[File:Keyhole.jpg|thumb|right|300px|The Keyhole as seen from the Boulder Field. A small stone shelter (Agnes Vaille Memorial) approximately 10 feet (3 m) high that sits on the left side of the Keyhole gives a sense of scale.]]
Trails that ascend Longs Peak include [[East Longs Peak Trail-Longs Peak Trail-Keyhole Route-Shelf Trail|the East Longs Peak Trail, the Longs Peak Trail, the Keyhole Route, Clark's Arrow and the Shelf Trail]]. Only some technical climbing is required to reach the summit of Longs Peak during the summer season, which typically runs from mid July through early September.  Outside of this window the popular "Keyhole" route is still open; however, its rating is upgraded to all "technical" as treacherous ice formation and snow fall necessitates the use of specialized climbing equipment including, at a minimum, [[crampons]] and an [[ice axe]].  It is one of the most difficult [[Yosemite Decimal System|Class 3]] fourteener scrambles in Colorado.<ref>{{cite web |title=Home of Colorado's Fourteeners and High Peaks |publisher=14ers.com |url=http://www.14ers.com}}</ref>
The hike from the trailhead to the summit is 8.4 miles (13.5&nbsp;km) each way, with a total elevation gain of 4,875 feet.  Most hikers begin before dawn in order to reach the summit and return below the [[tree line]] before frequent afternoon [[thunderstorm]]s bring a risk of [[lightning]] strikes. The most difficult portion of the hike begins at the Boulder Field, 6.4 miles (10&nbsp;km) into the hike. After scrambling over the boulders, hikers reach the Keyhole at 6.7 miles (10.5&nbsp;km).

The following quarter of a mile involves a scramble along narrow ledges, many of which may have nearly sheer cliffs of 1,000 feet (305 m) or more just off the edge. The next portion of the hike includes climbing over 600 vertical feet (183 m) up the Trough before reaching the most exposed section of the hike, the Narrows. Just beyond the Narrows, the Notch signifies the beginning of the Homestretch, a steep climb to the football field-sized, flat summit. It is possible to camp out overnight in the Boulder Field (permit required) which makes for a less arduous two-day hike. However, this is fairly exposed to the elements and requires an ascent of 3300&nbsp;ft over 6.4 miles with an overnight pack. Fifty-nine people have died climbing or hiking Longs Peak. According to the National Park Service, two people, on average, die every year attempting to climb the mountain.  Less experienced mountaineers are encouraged to use a guide for this summit to mitigate risk and increase the probability of a summit.

For hikers who do not wish to climb to the summit, there are less-involved hikes on the peak as well.  Peacock Pool and Chasm Lake are popular hiking destinations and follow well-maintained trails.  It is also rewarding to hike just to the Boulder Field, the Keyhole, or the seldom-visited Chasm View—the ridge between Mount Lady Washington and the east face of Longs Peak.  Camping is available at the Boulder Field and also on the lower portions of the mountain, such as Goblin's Forest next to the stream at the bottom.  Technical climbers, with the correct permit, are allowed to use sites at the base of the East Face and at Chasm View.  It is also possible to camp to the south of the mountain at Sand Beach Lake.

[[File:Longs Peak.jpg|thumb|left|Snowpack accumulation on Longs Peak]]
In addition to the standard "Keyhole" route, there are more serious and more technical climbs on Longs Peak.  Climbers should seek qualified instruction; deaths on Longs Peak are an annual occurrence. Some of the more common routes are, in approximate order of popularity,
* North Face Cables route:  This follows the Keyhole route to the Boulder Field, then ascends the North Face of the peak.  It requires one or two pitches of low-5th class climbing, and is often downclimbed or rappelled by technical climbers since it is one of the fastest ways to ascend or descend the peak.  In August of 1925, Walter Kiener submitted a proposal for fixed metal cables to be installed on this route to assist climbers, similar to systems in the [[Alps]].  The plan was approved by park superintendent Roger Toll and installed under the direction of park ranger Jack Moomaw. Two sections of 3/4 inch steel cable were installed (160 feet for the lower section and 31 feet for the upper section) using steel eye bolts drilled into the rocks.  The cables were removed in 1973 due to concerns about their appropriateness, but several of the bolts remain and are used as rappel anchors.<ref name=cableshistory>{{cite news|title=The Cables On Longs Peak|work=The Estes Park Trail|access-date=13 April 2025|date=20 July 1973|url=https://www.coloradohistoricnewspapers.org/?a=d&d=ETG19730720-01.2.38}}</ref><ref name=cablesremoval>{{cite news|title=Longs Peak Cable To Be Removed|work=The Estes Park Trail|access-date=13 April 2025|date=20 July 1973|url=https://www.coloradohistoricnewspapers.org/?a=d&d=ETG19730720-01.2.37}}</ref>
* Kieners Route:  A traditional mountaineering climb that involves a climb of Lambs Slide (named after Reverend [[Elkanah Lamb]] who unintentionally slid down much of the route in 1871<ref name="GuideTo14" />), which is icy later in the season, then an exposed traverse of the Broadway ledge, and then low-5th class climbing.
* via the Loft:  The Loft is the semipermanent snowfield between Longs Peak and its southeastern neighbor Mt. Meeker.  The saddle provides access to either peak.  One such traverse route is Gorrell's Traverse.<ref>A Climber's Guide to the Rocky Mountain National Park Area, Walt Fricke, 1971</ref>  It is also possible to ascend to the saddle via Lambs Slide. The 4th class Clark's Arrow route is also accessible via the Loft, ascending from the West side of the mountain, and later connecting with the Keyhole Route. 
* via the East Face:  The East Face is the steep, 1,000 + foot (305 + m) wall that includes the Diamond and the Lower East Face.  All climbs here are technical, from 5.10 to 5.13. It is also possible to ascend to the (climber's) left of the Diamond face proper. The routes on the right side of the Diamond are often [[aid climbing|aid climbed]], and may require spending the night on the wall; the rock here can be very wet. Routes on the left side of the Diamond are usually [[free climbing|free climbed]]. Only qualified climbers should attempt climbs on this face, and they should take into consideration the [[Acute Mountain Sickness|effects of altitude]] and alpine conditions in addition to the [[Yosemite Decimal System|difficulty rating]].
* via the Notch Couloir: This is a technical climb involving rock climbing and, at some times of year, [[ice climbing]]. The Notch Couloir is to the (climber's) left of the Diamond face.

==In literature==
Longs Peak is described in Jules Verne's [[From the Earth to the Moon]] as the location of a 16 feet (192-inch) reflecting telescope called "the Telescope of the Rocky Mountains", built for the purpose of tracking the Columbiad projectile on her flight to the Moon.
Englishwoman [[Isabella Bird]] extensively describes her joy of visiting Estes Park and climbing Longs Peak during her 1872 solo trip from San Francisco to the Rockies in "A Lady's Life in the Rocky Mountains".
