| 释义 |
The Petrified Dunes are a series of rock formations located in Arches National Park in southeastern Utah, United States.[1] The dunes can be found just off of the park road between the Courthouse Towers and the Windows Area. The formation was produced when ancient sand dunes hardened into stone under the overlying subsequent material, which later eroded away.[2] References1. ^{{cite web|url=http://www.go-utah.com/Arches-National-Park/|title=Arches National Park, Utah Travel Guide|website=go-Utah.com|publisher=Go Travel Sites|accessdate=2 Apr 2016}} 2. ^{{cite web|url=http://www.parksonline.org/parks/ada/arches/index.html|title=Arches National Park, UT|website=parksonline.org|publisher=America's Parks Online|accessdate=2 Apr 2016}} External links{{commons category-inline|Petrified Dunes (Arches National Park)}}{{coord|38|40|20|N|109|34|49|W|display=title}}{{Utah-geologic-formation-stub}} 3 : Landforms of Grand County, Utah|Arches National Park|Rock formations of Utah |
