Boucher Trail
The Boucher Trail is a hiking trail of the South Rim in Grand Canyon National Park, located in the U.S. state of Arizona. Access and description The trail officially begins at a low point on the Dripping Springs Trail, in the southwest part of Hermit Canyon. Access to the Boucher Trail requires a hike of about along the Hermit Trail and Dripping Springs Trail. Cairns exist in key places and can be spotted with some careful looking. The trail heads to the north and has little elevation change after leaving the Hermit Trail. There are a few short, sharp descents and climbs around minor rockfalls and washbeds. After about the trail contours around Yuma Point and heads southwestward until a sharp descent at the head of Travertine Canyon through the Supai Group. This descent steepens above 25% at places, which requires care to descend. Hikers descending in this area may need to exercise care as some points require steps down of . After the descent, the trail heads up for a sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Supai Group
The Supai Group is a slope-forming sequence of mixed red beds and limestones that outcrop 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 quite well exposed throughout the Grand Canyon in northwest Arizona, as well as local regions of southwest Utah, such as the Virgin River valley region. Known as the ''Supai Formation'', 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.Jenney, J.P., and Reynolds, S. J., ''Pennsylvanian and Permian geology of Arizona''.

Hermit
A hermit, also known as an eremite (adjectival form: hermitic or eremitic) or solitary, is a person who lives in seclusion. Eremitism plays a role in a variety of religions. Description In Christianity, the term was originally applied to a Christian who lives the eremitic life out of a religious conviction, namely the Catholic spirituality#Desert spirituality, Desert Theology of the Old Testament (i.e., the 40 years wandering in the Zin Desert, desert that was meant to bring about a change of heart). In the Christian tradition the eremitic life is an early form of Monk, monastic living that preceded the monastic life in the cenobium. In chapter 1, the Rule of St Benedict lists hermits among four kinds of monks. In the Roman Catholic Church, in addition to hermits who are members of religious institutes, the Canon law (Catholic Church), Canon law (canon 603) recognizes also Consecrated life#Other forms of consecrated life, diocesan hermits under the direction of their diocesan b ...

Louis Boucher (Grand Canyon)
Louis Boucher was a Canadian-born American prospector, miner, explorer, and guide in the Grand Canyon, Arizona in the late 19th to early 20th century. Life Louis Boucher was an American prospector who sought fortune in the Western US during the mid-1800s. Along with many others, Boucher left Canada during the gold rush. During his journey from the West to the Cariboo and Fraser areas of Canada, Boucher became familiar with the use of mules for transportation and gear-hauling. After a failed stint of gold prospecting in Cariboo, Boucher turned his attention to the southwest, seeking silver. Boucher eventually worked his way to the area now known as Arizona around 1889, and found work as a Grand Canyon guide for Hance Ranch, where he provided mule rides for canyon visitors. In 1891, Boucher decided to stake his own claim in the Grand Canyon, settling near Dripping Springs Basin, which provided a natural spring of fresh water to the canyon. Boucher built a camp for himself and a corr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potable Water
Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or consumed indirectly through food preparation. It is often (but not always) supplied through taps, in which case it is also called tap water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. For those who work in a hot climate, up to a day may be required. About 1 to 2 billion people lack safe drinking water. Water can carry vectors of disease and is a major cause of death and illness worldwide. Developing countries are most affected by unsafe drinking water. Sources Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commo ...

Dehydration
In physiology, dehydration is a lack of total body water that disrupts metabolic processes. It occurs when free water loss exceeds intake, often resulting from excessive sweating, health conditions, or inadequate consumption of water. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness in divers. Most people can tolerate a 3-4% decrease in total body water without difficulty or adverse health effects. A 5-8% decrease can cause fatigue and dizziness. Loss of over 10% of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs with a 15 and 25% loss of body water.Ashcroft F, Life Without Water in Life at the Extremes. Berkeley and Los Angeles, 2000, 134-138. Mild dehydration usually resolves with oral rehydration, but severe cases may need intravenous fluids. Dehydration can cause hypernatremia (high levels of sodium ions in the blood). This is distinct from hypovolemia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tapeats Sandstone
Except where underlain by the Sixtymile Formation, the Tapeats Sandstone is the Cambrian geologic formation that is the basal geologic unit of the Tonto Group. Typically, it is also the basal geologic formation of the Phanerozoic strata exposed in the Grand Canyon, Arizona, and parts of northern Arizona, central Arizona, southeast California, southern Nevada, and southeast Utah. The Tapeats Sandstone is about thick, at its maximum. The lower and middle sandstone beds of the Tapeats Sandstone are well-cemented, resistant to erosion, and form brownish, vertical cliffs that rise above the underlying Precambrian strata outcropping within Granite Gorge (Inner Gorge). They form the edge of the Tonto Platform. The upper beds of the Tapeats Sandstone form the surface of the Tonto Platform. The overlying soft shales and siltstones of the Bright Angel Shale underlie drab-greenish slopes that rise from the Tonto Platform to cliffs formed by limestones of the Muav Limestone and dolomites of ...

Tonto Platform
Tonto is a fictional character; he is the Native American (either Tonto Apache, Comanche, or Potawatomi) companion of the Lone Ranger, a popular American Western character created by George W. Trendle and Fran Striker. Tonto has appeared in radio and television series and other presentations of the characters' adventures righting wrongs in 19th-century western United States. Tonto made his first appearance on the 11th episode of the radio show, which originated on the Detroit, Michigan, radio station WXYZ. Though he became well known as the Lone Ranger's friend, Tonto was originally created just so the Lone Ranger would have someone to talk to. Throughout the radio run (which spanned 21 years), with only a few exceptions, Tonto was played by American actor John Todd. Chief Thundercloud played the character in the Republic movie serials ''The Lone Ranger'' and ''The Lone Ranger Rides Again''. To this point, Tonto had been depicted, on the radio series, as a somewhat elder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redwall Limestone
The Redwall Limestone is an erosion-resistant, Mississippian age, cliff-former, cliff-forming geological formation that forms prominent, red-stained cliffs in the Grand Canyon. these cliffs range in height from to . It is one of the most fossiliferous formations exposed in the Grand Canyon region. Nomenclature In 1875, GilbertGilbert, G.K., 1875. ''Report upon the geology of portions of Nevada, Utah, California, and Arizona, Chapter 6.'' In Wheeler, G.M., ed., pp. 17-187, ''Report on the Geographical and Geological Explorations and Surveys West of the One Hundredth Meridian'', vol. 3. U.S. Geological and Geographical Survey, Publication of the Wheeler Survey, Washington, D.C., 681 pp. recognized and named the Redwall Limestone for the red coloration of its escarpment on either side of Grand Canyon. As originally defined by him, it included some strata younger and older than as it is currently defined. Later in 1910, DartonDarton, N. H., 1910. ''A reconnaissance of parts of nort ...
