'''Landscape Arch''' is a [[natural arch]] in [[Arches National Park]], Utah, United States. It is among the longest natural rock arches in the world.<ref>{{cite web|title=What Is the Biggest Natural Arch in the World?|publisher=Utah Geological Survey|date=3 Aug 2016|url=https://geology.utah.gov/map-pub/survey-notes/what-is-the-biggest-natural-arch-in-the-world|archive-url=https://web.archive.org/web/20230404151203/https://geology.utah.gov/map-pub/survey-notes/what-is-the-biggest-natural-arch-in-the-world/ |archive-date=April 4, 2023|url-status=dead}}</ref>

==Description==
The arch is among many in the [[Devils Garden (Arches National Park)|Devils Garden]] area in the north of the park. Landscape Arch was named by Frank Beckwith who explored the area in the winter of 1933–1934 as the leader of an Arches National Monument scientific expedition. The arch can be reached by a {{cvt|0.8|mi|km}} graded gravel trail.<ref name="NABSBig91">{{cite web |url=http://www.naturalarches.org/big9-1.htm |title=Landscape Arch (NABS) |website=naturalarches.org |publisher=Natural Arch and Bridge Society |accessdate=May 20, 2009 |archive-date=February 24, 2007 |archive-url=https://web.archive.org/web/20070224082523/http://www.naturalarches.org/big9-1.htm |url-status=live }}</ref><ref name=trailguide>{{Cite web |url=https://www.nps.gov/arch/planyourvisit/upload/DevilsGardenTrailGuide2017-web.pdf |title=Devils Garden Trail Guide – A Changing Landscape: Naturally |website=nps.gov |publisher=[[National Park Service]] |accessdate=March 12, 2017 |archive-date=August 4, 2017 |archive-url=https://web.archive.org/web/20170804052942/https://www.nps.gov/arch/planyourvisit/upload/DevilsGardenTrailGuide2017-web.pdf |url-status=live }}</ref>

The Natural Arch and Bridge Society (NABS) considers Landscape Arch the fifth longest natural arch in the world, after four arches in China.<ref>{{cite web |url=http://www.naturalarches.org/big9.htm |title=The Worlds Longest Natural Spans |website=www.naturalarches.org |publisher=Natural Arch and Bridge Society |accessdate=May 3, 2016 |archive-date=December 25, 2016 |archive-url=https://web.archive.org/web/20161225013414/http://www.naturalarches.org/big9.htm |url-status=live }}</ref> In 2004, the span of Landscape Arch was measured at {{cvt|290.1|ft|m}}, ±{{cvt|0.8|ft|m}}, with a height of 77.5 ft (23.6 m).<ref>{{cite web |url=http://www.naturalarches.org/archinfo/landscape.htm |title=The Dimensions of Landscape Arch |last=Wilbur |first=Jay H |website=naturalarches.org |publisher=Natural Arch and Bridge Society |accessdate=November 12, 2008 |archive-date=February 19, 2007 |archive-url=https://web.archive.org/web/20070219073227/http://www.naturalarches.org/archinfo/landscape.htm |url-status=live }}</ref> NABS measured the span of the slightly shorter [[Kolob Arch]] in [[Zion National Park]] at {{cvt|287|ft|m}} in 2006.<ref>{{cite web |url=http://www.naturalarches.org/archinfo/kolob.htm |title=The Dimensions of Kolob Arch |last=Wilbur |first=Jay H |website=naturalarches.org |publisher=Natural Arch and Bridge Society |accessdate=November 12, 2008 |archive-date=April 27, 2021 |archive-url=https://web.archive.org/web/20210427025022/http://www.naturalarches.org/archinfo/kolob.htm |url-status=live }}</ref>
