Please answer the following question: Information:  - Utah (or ) is a state in the western United States. It became the 45th state admitted to the U.S. on January 4, 1896. Utah is the 13th-largest by area, 31st-most-populous, and 10th-least-densely populated of the 50 United States. Utah has a population of more than 3 million (Census estimate for July 1, 2016), approximately 80% of whom live along the Wasatch Front, centering on the state capital Salt Lake City. Utah is bordered by Colorado to the east, Wyoming to the northeast, Idaho to the north, Arizona to the south, and Nevada to the west. It also touches a corner of New Mexico in the southeast.  - Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains.  - The Courthouse Towers is a collection of tall stone columns located in Arches National Park.  - Arches National Park is a US National Park in eastern Utah. The park is adjacent to the Colorado River, north of Moab, Utah. It is home to over 2,000 natural sandstone arches, including the world-famous Delicate Arch, in addition to a variety of unique geological resources and formations. It contains the highest density of natural arches in the world.  - The Colorado River ("colored", with an implication of reddish) is one of the principal rivers of the Southwestern United States and northern Mexico (the other being the Rio Grande). The Colorado River drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains in the U.S., the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the ArizonaNevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.   - Delicate Arch is a freestanding natural arch located in Arches National Park near Moab, Utah, USA. It is the most widely recognized landmark in Arches National Park and is depicted on Utah license plates and on a postage stamp commemorating Utah's centennial anniversary of admission to the Union in 1996. The Olympic torch relay for the 2002 Winter Olympics passed through the arch.  - A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term column applies especially to a large round support (the "shaft" of the column) with a capital and a "base" or pedestal and made of stone, or appearing to be so. A small wooden or metal support is typically called a post, and supports with a rectangular or other non-round section are usually called piers. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces. Other compression members are often termed "columns" because of the similar stress conditions. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. In architecture, "column" refers to such a structural element that also has certain proportional and decorative features. A column might also be a decorative element not needed for structural purposes; many columns are "engaged", that is to say form part of a wall.  - The Petrified Dunes are a series of rock formations located in Arches National Park . 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 .  - Moab is a city in Grand County, in eastern Utah, in the western United States. The population was 5,046 at the 2010 census. It is the county seat and largest city in Grand County. Moab attracts a large number of tourists every year, mostly visitors to the nearby Arches and Canyonlands National Parks. The town is a popular base for mountain bikers who ride the extensive network of trails including Slickrock Trail, and off-roaders who come for the annual Moab Jeep Safari.    Given the information above, choose from the list below the object entity that exhibits the relation 'located in the administrative territorial entity' with the subject 'petrified dunes'.  Choices: - california  - canyon  - colorado  - east  - grand county  - mexico  - most  - mountain  - national park  - north  - northern  - of  - post  - rio  - river  - rock  - southwest  - union  - utah  - west  - wyoming
