Swilling Butte
Swilling Butte is a -elevation ridgeline summit located in the eastern Grand Canyon, in Coconino County of northern Arizona, United States. The landform is in a group of nearby summits, Colter Butte, west, and Hutton and Duppa Buttes, east. All four buttes are at the north of the east-flowing Kwagunt Creek and Canyon drainage to the Colorado River. Swilling Butte is northeast of Atoko Point, East Rim of the Walhalla Plateau (Kaibab Plateau, North Rim), and west of the (north)-East Rim, Grand Canyon; the south-flowing Colorado River is west and adjacent to the East Rim. Swilling Butte is a triangular-platform summit of bright-red, tall Redwall Limestone. Being a cliff-former, the Redwall is also a platform-former. The upper platform of the Redwall Limestone supports a remainder-debris of the Supai Group (a 4-unit group). Of the two lower units, no. 2 is a cliff-former, hard rocks (cliffs), of the Manakacha Formation; the slope-former, (unit no. 1), the Watahomigi Formation, forms ...

Colter Butte
Colter Butte is a summit located in the Grand Canyon in Coconino County of northern Arizona, US. It is situated four miles southeast of Point Imperial, where it towers above Nankoweap Canyon. Its neighbors include Brady Peak, 2.5 miles to the west-northwest, Alsap Butte two miles to the northwest, and Swilling Butte one-half mile to the east. Colter Butte is named after James G. H. Colter (1844–1922), born in Nova Scotia, Canada, he came to the Arizona Territory in 1872 as a pioneer, farmer, cattleman, Apache and desperado fighter. He was the father of Arizona state senator Fred Colter. This geographical feature's name was officially adopted in 1932 by the United States Board on Geographic Names. According to the Köppen climate classification system, Colter Butte is located in a cold semi-arid climate zone. This butte is composed of Pennsylvanian- Permian Supai Group which overlays cliff-forming Mississippian Redwall Limestone, which in turn overlays slope-forming Camb ...

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 stratigraphi ...

Harvey Butchart
John Harvey Butchart (May 10, 1907 – May 29, 2002) was a mathematics professor who was well known for his hiking exploits in and around the Grand Canyon in Arizona, United States. Beginning in 1945, Butchart explored the Grand Canyon's backcountry on foot. He wrote extensively about his adventures and influenced generations of canyoneers. Sparse human communities have lived, worked, and traveled in the harsh and beautiful Canyon terrain at least since the Ancestral Puebloans. Native Americans occupied parts of the canyon in the mid 1800s when American explorers first arrived, followed over time by prospectors, miners, researchers, and the outdoor tourists who now dominate the community. Most of the millions of visitors to Grand Canyon National Park remain in the developed South and North Rim areas. A smaller number hike into the Canyon along a few well-maintained trails. A very small number venture beyond, into the true wilderness of the Park. Harvey Butchart led the way, usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slope-former
A slope-former is a unit of bedrock which is less resistant to erosion than overlying or underlying units and consequently results in outcrops with low relative slope angles. It may be contrasted with cliff-former. Typical slope forming lithologies include shales, and limestone Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime.

Manakacha Formation
The (Upper) Late Pennsylvanian Manakacha Formation is a cliff-forming, sandstone, red-orange geologic unit, formed from an addition of eolian sand, added to marine transgression deposits, (siltstones, etc.), and found throughout sections of the Grand Canyon. It is one of the lower members of the Supai Group (member two of four major units), with the Supai Group found in other sections of Arizona, especially in the Verde Valley region, or as a basement unit below the Mogollon Rim, just eastwards or part of the basement Supai Group of the southwest & south Colorado Plateau. The Manakacha Formation was laid down (especially in the Grand Canyon). It consists of up to of calcareous sandstone and shaly mudstone. It represents a time when deposition of aeolian sand became more widespread. The Manakacha was deposited at about the same time as the Weber Sandstone was deposited in northeast Utah in Dinosaur National Monument region, northeast of the Uncompahgre Uplift. This was likel ...

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, Pocono, and Pottsville Pottsville usually refers to the city of Pottsville, Pennsylvania, in the United States. Pottsville may also refer to: Other communities *Pottsville, New South Wales, Australia *Pottsville, Arkansas, United States *Pottsville, Kentucky, United ... Formations.

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada 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. Known for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River and its tributaries are a vital source of water for 40 million people.

Grand Canyon
The Grand Canyon (, yuf-x-yav, Wi:kaʼi:la, , Southern Paiute language: Paxa’uipi, ) is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is long, up to wide and attains a depth of over a mile (). The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.

Bright Angel Shale
The Cambrian Bright Angel Shale is the middle layer of the three member Tonto Group geologic feature. The 3-rock Tonto section famously sits upon the Great Unconformity because of the highly resistant cliffs of the base layer, vertical Tapeats Sandstone cliffs. The Bright Angel Shale is easily identified for two reasons. Its soft-greenish color stands out against the browns, reds, and whites of neighboring rock units. And secondly for its slope-forming character against mostly cliff-forming resistant rocks. The Bright Angel Shale is about thick at its maximum. It is a nonresistant slope-forming unit. The Bright Angel Shale consists of green and purple-red, siltstone and shale which is interbedded with red-brown to brown sandstone that is similar in lithology to the underlying Tapeats Sandstone.Connors, T.B., Tweet, J.S., and Santucci, V.L., 2020.
