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]

Utah 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, 30th-most-populous, and 11th-least-densely populated of the 50 United States. Utah has a population of more than 3 million according to the Census estimate for July 1, 2016. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which contains approximately 2.5 million people; and Washington County in Southern Utah, with over 160,000 residents. 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.
The United States of America (USA), commonly known as the United States or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.
Landscape Arch is the longest of the many natural rock arches located in Arches National Park, Utah, United States.

The Entrada Sandstone is a formation in the San Rafael Group that is found in the U.S. states of Wyoming, Colorado, northwest New Mexico, northeast Arizona and southeast Utah. Part of the Colorado Plateau, this formation was deposited during the Jurassic period sometime between 180 and 140 million years ago in various environments, including tidal mudflats, beaches and sand dunes. The Middle Jurassic San Rafael Group was dominantly deposited as ergs in a desert environment around the shallow Sundance Sea.
Canyonlands National Park is an American national park located in southeastern Utah near the town of Moab. The park preserves a colorful landscape eroded into numerous canyons, mesas, and buttes by the Colorado River, the Green River, and their respective tributaries. Legislation creating the park was signed into law by President Lyndon Johnson on September 12, 1964.
Double Arch is a close-set pair of natural arches in Arches National Park in southern Grand County, Utah, United States, that is one of the more known features of the park.
The exposed geology of the Canyonlands area is complex and diverse; 12 formations are exposed in Canyonlands National Park that range in age from Pennsylvanian to Cretaceous. The oldest and perhaps most interesting was created from evaporites deposited from evaporating seawater. Various fossil-rich limestones, sandstones, and shales were deposited by advancing and retreating warm shallow seas through much of the remaining Paleozoic.
The exposed geology of the Capitol Reef area presents a record of mostly Mesozoic-aged sedimentation in an area of North America in and around Capitol Reef National Park, on the Colorado Plateau in southeastern Utah.
Westwater Canyon is a canyon located on the Colorado River in Eastern Utah between the Utah/Colorado state line and Cisco, Utah. The inner gorge of the canyon is made up of black Precambrian rock and contains class III and IV rapids which are sought after by whitewater enthusiasts.

Snow Canyon State Park is a state park of Utah, USA, featuring a canyon carved from the red and white Navajo sandstone in the Red Mountains. The park is located near Ivins, Utah and St. George in Washington County. Other geological features of the state park include extinct cinder cones, lava tubes, lava flows, and sand dunes.
The Chinle Formation is an Upper Triassic continental geologic formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. The Chinle is controversially considered to be synonymous to the Dockum Group of eastern Colorado and New Mexico, western Texas, the Oklahoma panhandle, and southwestern Kansas. The Chinle is sometimes colloquially named as a formation within the Dockum Group in New Mexico and in Texas. The Chinle Formation is part of the Colorado Plateau, Basin and Range, and the southern section of the Interior Plains.

Escalante Petrified Forest State Park is a state park of Utah, USA, located a half-mile (0.8 km) north of the town of Escalante. A visitor center was built in 1991, and features displays of plant and marine fossils, petrified wood and fossilized dinosaur bones over 150 million years old. The Petrified Forest Trail is a one-mile (1.6 km) loop, winding up the side of a mesa to the top where most of the fossil wood occurs. Logs two feet or more in diameter are seen at several places along the trail where it is eroding from the conglomerate capping the mesa. This conglomerate lies near the top of the Brushy Basin Member of the Morrison Formation. The wood is multicolored and was prized by hobbyists before the Park was established. The logs are believed to be of conifers that were transported by a river before being buried and later fossilized as agate. A 50 foot (15m) log is displayed near the trail head and is one of the most complete fossil logs known from the Morrison Formation.

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
