Supai Group
The Supai Group is a slope-forming section of red bed deposits found in the Colorado Plateau. The group was laid down during the Pennsylvanian to Lower Permian. Cliff-forming interbeds of sandstone are noticeable throughout the group. The Supai Group is especially exposed throughout the Grand Canyon in northwest Arizona, as well as local regions of southwest Utah, such as the Virgin River valley region. It occurs in Arizona at Chino Point, Sycamore Canyon, and famously at Sedona as parts of Oak Creek Canyon. In the Sedona region, it is overlain by the Hermit Formation, and the colorful Schnebly Hill Formation. The Supai Group is coeval with the Hermosa Group of east and south Utah; the Hermosa Group extended southeastwards from Utah to Durango, extreme southwest Colorado, and adjacent to the Hermosa type section. The Supai Group was originally designated as the Supai Formation by N.H. Darton in 1910 for exposures at Supai, Arizona. It was first raised to group stratigrap ...

Red Beds
Red beds (or redbeds) are sedimentary rocks, typically consisting of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of ferric oxides. Frequently, these red-colored sedimentary strata locally contain thin beds of conglomerate, marl, limestone, or some combination of these sedimentary rocks. The ferric oxides, which are responsible for the red color of red beds, typically occur as a coating on the grains of sediments comprising red beds. Classic examples of red beds are the Permian and Triassic strata of the western United States and the Devonian Old Red Sandstone facies of Europe. Primary red beds Primary red beds may be formed by the erosion and redeposition of red soils or older red beds, but a fundamental problem with this hypothesis is the relative scarcity of red-colored source sediments of suitable age close to an area of red-bed sediments in Cheshire, England. Primary red beds may also form by in situ (early diagenetic) redd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naco Formation
The Naco Formation is a geologic formation in Arizona. It preserves fossils dating back to the Pennsylvanian subperiod. Fossils from the Kohls Ranch locality of Gila County, Arizona, include bivalve and gastropod molluscs, brachiopods, bryozoans, crinoids, cnidarians and sharks teeth.Brew, D. C. and S.

Schnebly Hill Formation
The Schnebly Hill Formation is a section of red bed deposits found at the Colorado Plateau, near Sedona, Arizona. It is a dark red sandstone, from to thick. It lies between Coconino Sandstone and the older Hermit Formation. It is near the Supai Group. The source of the name "Schnebly" is Sedona Schnebly, after whom the city of Sedona, Arizona was named. Geology The formation traces to the Permian Age. The formation is the most prominent layer of the red rocks of the Sedona area due the presence of hematite – iron-oxide, frankly, rust – giving the sandstone a red color. The Schnebly Hill Sandstone formation comprises three sections: * the Bell Rock member, * the Fort Apache member, and * the Sycamore Pass member.

Oak Creek Canyon
Oak Creek Canyon is a river gorge located in northern Arizona between the cities of Flagstaff and Sedona. The canyon is often described as a smaller cousin of the Grand Canyon because of its scenic beauty. State Route 89A enters the canyon on its north end via a series of hairpin turns before traversing the bottom of the canyon for about until the highway enters the town of Sedona. Geography Oak Creek Canyon is about long, ranging in width from . The depth of the canyon ranges from . However, due to the faulting that played a major role in its formation, the west rim of the canyon is higher than the east rim. The average elevation of the west rim is while the east rim elevation is . Oak Creek Oak Creek, a tributary of the Verde River, flows along the bottom of the canyon, and is one of the few perennial streams in the high desert region of northern Arizona. Oak Creek is largely responsible for carving the modern Oak Creek Canyon, although movement along the Oak Creek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedona, Arizona
Sedona is a city that straddles the county line between Coconino and Yavapai counties in the northern Verde Valley region of the U.S. state of Arizona. As of the 2010 census, its population was 10,031. It is within the Coconino National Forest. Sedona's main attraction is its array of red sandstone formations. The formations appear to glow in brilliant orange and red when illuminated by the rising or setting sun. The red rocks form a popular backdrop for many activities, ranging from spiritual pursuits to the hundreds of hiking and mountain biking trails. Sedona is also the home to the nationally recognized McDonald's with turquoise arches, instead of the traditional Golden Arches. Sedona was named after Sedona Arabella Miller Schnebly (1877–1950), the wife of Theodore Carlton Schnebly, the city's first postmaster. She was celebrated for her hospitality and industriousness. Her mother, Amanda Miller, claimed to have made the name up because "it sounded pretty". Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utah
Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin. Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute. The Spanish were the first Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arizona
Arizona ( ; nv, Hoozdo Hahoodzo ; ood, Alĭ ṣonak ) is a state in the Southwestern United States. It is the 6th largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is part of the Four Corners region with Utah to the north, Colorado to the northeast, and New Mexico to the east; its other neighboring states are Nevada to the northwest, California to the west and the Mexican states of Sonora and Baja California to the south and southwest. Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. Historically part of the territory of in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase. Southern Arizona is known for its desert cl ...

Cliff-former
A cliff-former is a geological unit of bedrock that is more resistant to erosion than overlying or underlying strata and consequently produces outcrops with high slope angles. It is more or less equivalent to ''ridge-former'', and may be contrasted with slope-former. In humid environments, sandstones are typically cliff-formers. In arid environments, limestones are often cliff-formers also. Recent lavas may be cliff-formers as well. In the Ridge-and-Valley Appalachians of the eastern United States the major ridge-formers are the Tuscarora Tuscarora may refer to the following: First nations and Native American people and culture * Tuscarora people **''Federal Power Commission v.

Verde Valley
The Verde Valley ( yuf-x-yav, Matkʼamvaha; es, Valle Verde) is a valley in central Arizona in the United States. The Verde River runs through it. The Verde River is one of Arizona's last free-flowing river systems. It provides crucial habitat for fish and wildlife, fresh water for local agricultural production, recreational opportunities for locals and tourists alike, and brings clean drinking water to over 2 million people in the greater Phoenix area. The valley is overlooked by Mingus Mountain and the Mogollon Rim. The valley is one of three regions of viticulture in Arizona and contains the Verde Valley AVA. History The first notice of this region appears in the report of Antonio de Espejo, who visited in 1583. Little more was recorded until the commencement of prospecting for gold and silver in the 19th century.
