The geology of Utah, in the western United States, includes rocks formed at the edge of the proto-North American continent during the Precambrian.A shallow marine sedimentary environment covered the region for much of the Paleozoic and Mesozoic, followed by dryland conditions, volcanism, and the formation of the basin and range terrain in the Cenozoic.
Newspaper Rock in 1972. Newspaper Rock State Historic Monument is a Utah state monument featuring a rock panel carved with one of the largest known collections of petroglyphs. [1] It is located in San Juan County, along Utah State Route 211, 28 miles (45 km) northwest of Monticello and 53 miles (85 km) south of Moab.
The distinct shapes of these rocks result from an erosion-resistant layer of rock atop relatively softer sandstone. Goblin Valley State Park and Bryce Canyon National Park, also in Utah about 190 miles (310 km) to the southwest, contain some of the largest occurrences of hoodoos in the world.
Outcrops of this brightly colored red, brown, and pink banded formation can be seen in the Kolob Canyons section of the park and in buttes on either side of State Route 9 between Rockville, Utah, to the south and Virgin, Utah, to the southwest of the park borders. Progressively higher beds are exposed until the top of the formation is reached ...
Nearly 10,000 feet (3,000 m) of sedimentary strata are found in the Capitol Reef area, representing nearly 200 million years of geologic history of the south-central part of the U.S. state of Utah. These rocks range in age from Permian (as old as 270 million years old) to Cretaceous (as young as 80 million years old.) [1] Rock layers in the ...
The San Rafael Swell was formed when deeply buried Precambrian rocks faulted, or broke, during the Laramide orogeny, about 60 million years ago. These "basement" rocks below the present-day Swell moved upwards relative to the surrounding areas and caused the overlying sedimentary rocks to fold into a dome-like shape called an anticline. The ...
The marine and fluvial metasedimentary rocks in the core of the Uinta Mountains are of Neoproterozoic age [3] (between about 700 million and 760 million [4] years old) and consist primarily of quartzite, slate, and shale. These rocks comprise the Uinta Mountain Group, and reach thicknesses of 13,000 to 24,000 feet (4.0 to 7.3 km). Most of the ...
View from Utah Highway 12 of Grand Staircase–Escalante National Monument. The Grand Staircase is an immense sequence of sedimentary rock layers that stretches south from Bryce Canyon National Park and Grand Staircase–Escalante National Monument, through Zion National Park, and into Grand Canyon National Park.
