Devils Tower

Indigenous names for the monolith include "Bear's House" or "Bear's Lodge" (or "Bear's Tipi", "Home of the Bear", "Bear's Lair"); Cheyenne, {{langx|lkt|Matȟó Thípila}}, {{langx|cro|Daxpitcheeaasáao}} ("Home of Bears"{{cite web |title=Little Big Horn College Library |url=http://lib.lbhc.edu/placenames.php?q=Daxpitcheeaas%E1ao&d=&s=&submit=Go |access-date=June 5, 2012}}), "Aloft on a Rock" (Kiowa), "Tree Rock", "Great Gray Horn", and "Brown Buffalo Horn" ({{langx|lkt|Ptehé Ǧí}}).{{citation needed|date=January 2017}}

The name "Devil's Tower" originated in 1875 during an expedition led by Colonel Richard Irving Dodge, when his interpreter reportedly misinterpreted a native name to mean "Bad God's Tower"."Why is it called Devils Tower? Some Native Americans called it Mato Tipila, meaning Bear Lodge. Other Native American names include Bear's Tipi, Home of the Bear, Tree Rock and Great Gray Horn. In 1875, on an expedition led by Col. Dodge, it is believed his interpreter misinterpreted the name to mean Bad God's Tower, later shortened to Devils Tower."

All information signs in that area use the name "Devils Tower", following a geographic naming standard whereby the apostrophe is omitted."Since its inception in 1890, the U.S. Board on Geographic Names has discouraged the use of the possessive form—the genitive apostrophe and the 's'.

In 2005, a proposal to recognize several indigenous ties through the additional designation of the monolith as Bear Lodge National Historic Landmark were opposed by United States Representative Barbara Cubin, arguing that a "name change will harm the tourist trade and bring economic hardship to area communities".{{cite web |url=http://www.house.gov/cubin/news/2005/March08e.html |title=Cubin Fights Devils Tower Name Change |access-date=July 22, 2008 |archive-url=https://web.archive.org/web/20081226230212/http://www.house.gov/cubin/news/2005/March08e.html |archive-date=December 26, 2008}} In November 2014, Arvol Looking Horse proposed renaming the geographical feature "Bear Lodge" and submitted the request to the United States Board on Geographic Names. A second proposal was submitted to request that the U.S. acknowledge what it described as the "offensive" mistake in keeping the current name and to rename the monument and sacred site into Bear Lodge National Historic Landmark. The formal public comment period ended in fall 2015.

The landscape surrounding Devils Tower is composed mostly of sedimentary rocks. The oldest rocks visible in Devils Tower National Monument were laid down in a shallow sea during the Triassic. This dark red sandstone and maroon siltstone, interbedded with shale, can be seen along the Belle Fourche River. Oxidation of iron minerals causes the redness of the rocks. This rock layer is known as the Spearfish Formation. Above the Spearfish Formation is a thin band of white gypsum, called the Gypsum Springs Formation, Jurassic in age. Overlying this formation is the Sundance Formation.{{cite journal|journal=United States Geological Survey|last1=Robinson |first1=Charles |title=Geology of Devils Tower National Monument, USGS Bulletin 1021-I |url=https://pubs.er.usgs.gov/publication/b1021I |publisher=USGS |access-date=14 April 2021 |date=1956|doi=10.3133/b1021I |doi-access=free }} During the Paleocene Epoch, 56 to 66 million years ago, the Rocky Mountains and the Black Hills were uplifted. Magma rose through the crust, intruding into the existing sedimentary rock layers.[http://www.nps.gov/deto/naturescience/geologicformations.htm National Park Service: Devils Tower: Geologic Formations]

Geologists Carpenter and Russell studied Devils Tower in the late 19th century and came to the conclusion that it was formed by an igneous intrusion.{{cite book | url=https://books.google.com/books?id=q84_AAAAIAAJ&dq=carpenter+russell+%22devils+tower%22+igneous&pg=PP20 | title=A Report on the Geology of Devils Tower National Monument | pages=10 | author=Effinger, William Lloyd | year=1934 | publisher=U.S. Department of the Interior }} In 1907, geologists Nelson Horatio Darton and C.C.

As rain and snow continue to erode the sedimentary rocks surrounding the Tower's base, more of Devils Tower will be exposed. Nonetheless, the exposed portions of the Tower still experience certain amounts of erosion. Cracks along the columns are subject to water and ice erosion. Portions, or even entire columns, of rock at Devils Tower are continually breaking off and falling. Piles of broken columns, boulders, small rocks, and stones, called scree, lie at the base of the tower, indicating that it was once wider than it is today.

Devils Tower inspired many geomyths.

According to the traditional beliefs of Native American peoples, the Kiowa and Lakota, a group of girls went out to play and were spotted by several giant bears, who began to chase them. In an effort to escape the bears, the girls climbed atop a rock, fell to their knees, and prayed to the Great Spirit to save them. Hearing their prayers, the Great Spirit made the rock rise from the ground towards the heavens so that the bears could not reach the girls. The bears, in an effort to climb the rock, left deep claw marks in the sides, which had become too steep to climb. Those are the marks which appear today on the sides of Devils Tower. When the girls reached the sky, they were turned into the stars of the Pleiades.Robert Burnham, Jr.: Burnham's Celestial Handbook, Vol. 3, p. 1867

Another version tells that two Sioux boys wandered far from their village when Mato the bear, a huge creature that had claws the size of tipi poles, spotted them, and wanted to eat them for breakfast. He was almost upon them when the boys prayed to Wakan Tanka the Creator to help them. They rose up on a huge rock, while Mato tried to get up from every side, leaving huge scratch marks as he did. Finally, he sauntered off, disappointed and discouraged. The bear came to rest east of the Black Hills at what is now Bear Butte. Wanblee, the eagle, helped the boys off the rock and back to their village. A painting depicting this legend by artist Herbert A. Collins hangs over the fireplace in the visitor center at Devils Tower.

In a Cheyenne version of the story, the giant bear pursues the girls and kills most of them. Two sisters escape back to their home with the bear still tracking them. They tell two boys that the bear can only be killed with an arrow shot through the underside of its foot. The boys have the sisters lead the bear to Devils Tower and trick it into thinking they have climbed the rock. The boys attempt to shoot the bear through the foot while it repeatedly attempts to climb up and slides back down leaving more claw marks each time. The bear was finally scared off when an arrow came very close to its left foot. This last arrow continued to go up and never came down.Marquis, pp. 53–54

Wooden Leg, a Northern Cheyenne, related another legend told to him by an old man as they were traveling together past the Devils Tower around 1866–1868. An Indigenous man decided to sleep at the base of Bear Lodge next to a buffalo head. In the morning he found that both he and the buffalo head had been transported to the top of the rock by the Great Medicine with no way down. He spent another day and night on the rock with no food or water. After he had prayed all day and then gone to sleep, he awoke to find that the Great Medicine had brought him back down to the ground, but left the buffalo head at the top near the edge. Wooden Leg maintained that the buffalo head was clearly visible through the old man's spyglass. At the time, the tower had never been climbed and a buffalo head at the top was otherwise inexplicable.Marquis, pp. 54–55

The buffalo head gives this story special significance for the Northern Cheyenne. All the Cheyenne maintained in their camps a sacred teepee to the Great Medicine containing the tribal sacred objects. In the case of the Northern Cheyenne, the sacred object was a buffalo head.Marquis pp. 106, 152

N. Scott Momaday (Kiowa) was given the name Tsoai-talee (Rock Tree Boy) by Pohd-lohk, a Kiowa elder, linking the child to the Devils Tower bear myth. To reinforce this mythic connection, his parents took him there.{{cite web |title=N.

Fur trappers may have visited Devils Tower, but they left no written evidence of having done so. The first documented non-Indigenous visitors were members of Captain William F. Raynolds's 1859 expedition to Yellowstone. Sixteen years later, Colonel Richard I. Dodge escorted an Office of Indian Affairs scientific survey party to the massive rock formation and coined the name Devils Tower.{{cite book|last=Dodge|first=Richard|title=The Black Hills journals of Colonel Richard Irving Dodge|year=1996|publisher=University of Oklahoma Press|isbn=0-8061-2846-1|url=https://books.google.com/books?id=ggv-JLih54AC|editor=Wayne R.

As of 1994, climbing Devils Tower had increased in popularity. About 1.3% of the monument's 400,000 annual visitors climbed Devils Tower, mostly using traditional climbing techniques.[http://www.nps.gov/deto/planyourvisit/loader.cfm?csModule=security/getfile&PageID=514740 Devils Tower NM – Final Climbing Management Plan] {{Webarchive|url=https://web.archive.org/web/20111110034346/http://www.nps.gov/deto/planyourvisit/loader.cfm?csModule=security%2Fgetfile&PageID=514740 |date=November 10, 2011 }} National Park Service, page 4, February 1995, accessed March 13, 2009 The first known ascent of Devils Tower by any method occurred on July 4, 1893, and is credited to William Rogers and Willard Ripley, local ranchers in the area. They completed this first ascent after constructing a ladder of wooden pegs driven into cracks in the rock face. A few of these wooden pegs are still intact and are visible on the tower when hiking along the {{convert|1.3|mi|km|adj=on}} Tower Trail at Devils Tower National Monument. Over the following 30 years, many climbs were made using this method before the ladder fell into disrepair.

The first ascent using modern climbing techniques was made by Fritz Wiessner with William P. House and Lawrence Coveney in 1937. Wiessner led almost the entire climb free, placing only a single piece of fixed gear, a piton, which he later regretted, deeming it unnecessary.

In 1941 George Hopkins parachuted onto Devils Tower,{{Cite web|url=https://www.nps.gov/deto/learn/historyculture/first-fifty-years-george-hopkins.htm|title = Parachutist George Hopkins – Devils Tower National Monument (U.S. National Park Service)}} without permission, as a publicity stunt resulting from a bet. He had intended to descend by a {{convert|1,000|ft|m|adj=on}} rope dropped to him after successfully landing on the butte, but the package containing the rope, a sledge hammer and a car axle to be driven into the rock as an anchor point slid over the edge. As the weather deteriorated, a second attempt was made to drop equipment, but Hopkins deemed it unusable after the rope became snarled and frozen due to the rain and wind. Hopkins was stranded for six days, exposed to cold, rain and {{cvt|50|mph|km/h}} winds before a mountain rescue team led by Jack Durrance, who had successfully climbed Devils Tower in 1938, finally reached him and brought him down.{{cite book |first=John Darwin |last=Dorst |title=Looking West |page=202 |publisher=University of Pennsylvania Press |year=1999 |isbn=0812214404}}{{cite news |url=https://news.google.com/newspapers?id=6zwcAAAAIBAJ&sjid=01oEAAAAIBAJ&pg=4384,3275166 |title=Parachutist gains five pounds while stranded on rock |newspaper=The Victoria Advocate |date=October 7, 1941 |agency=United Press |access-date=February 15, 2021}} His entrapment and rescue was widely covered by the media of the time.See for instance, {{cite news |url=https://select.nytimes.com/gst/abstract.html?res=FA0915F73A5B147B93C5A9178BD95F458485F9 |title=Alpinists bring down man on Devil's Tower; 'rather go back than face crowd,' he says |newspaper=The New York Times |page=25 |date=October 7, 1941 |url-access=subscription}}

Today, hundreds of climbers scale the sheer rock walls of Devils Tower each summer. The most common route is the Durrance Route, which was the second free route established in 1938. There are many established and documented climbing routes covering every side of the tower, ascending the various vertical cracks and columns of the rock. The difficulty of these routes range from relatively easy to some of the most challenging in the world. All climbers are required to register with a park ranger before and after attempting a climb. No overnight camping at the summit is allowed; climbers return to base on the same day they ascend.{{Cite web |url=http://www.devilstowerclimbing.com/climbing/ |title=devilstowerclimbing.com |access-date=October 20, 2014 |archive-date=October 7, 2014 |archive-url=https://web.archive.org/web/20141007085427/http://www.devilstowerclimbing.com/climbing/ |url-status=dead }}{{full citation needed|date=February 2021}}

The Tower is sacred to several Plains tribes, including the Lakota, Cheyenne and Kiowa. Because of this, many Native American leaders objected to climbers ascending the monument, considering this to be a desecration. The climbers argued that they had a right to climb the Tower, since it is on federal land. A compromise was eventually reached with a voluntary climbing ban during the month of June when the tribes are conducting ceremonies around the monument. Climbers are asked, but not required, to stay off the Tower in June. According to the PBS documentary In the Light of Reverence, approximately 85% of climbers honor the ban and voluntarily choose not to climb the Tower during the month of June. However, several climbers along with the Mountain States Legal Foundation sued the Park Service, claiming an inappropriate government entanglement with religion.[https://web.archive.org/web/20040820181334/http://www.sacredland.org/ITLOR_pages/three_stories.html Sacred Land Film Project], Devils Tower.{{full citation needed|date=February 2021}}{{Cite web|url=https://www.outsideonline.com/2329411/why-its-time-rethink-climbing-ban-devils-tower|title=It's Time to Rethink Climbing on Devils Tower|last=Kalman|first=Chris|date=July 25, 2018|website=Outside Online|language=en|access-date=May 2, 2019}}
