List Of Trails In Grand Canyon National Park
The following is a list of hiking trails that are, in whole or part, within the established boundaries of Grand Canyon National Park, located in Coconino and Mohave counties in the U.S. state of Arizona. Management All pack and foot trails in Grand Canyon National Park fall under the jurisdiction of the Grand Canyon Backcountry Office (BCO), located in the Backcountry Information Center in Grand Canyon Village. This building previously housed a railway depot. The BCO administers trail maintenance, patrol, and search and rescue operations in the Grand Canyon's backcountry areas. The Grand Canyon Backcountry Office manages undeveloped areas of the canyon by following the 1988 Backcountry Management Plan (BMP), as amended. The goal of the plan is to mitigate human impacts to ecologically sensitive areas within the park. In those areas, the BMP provides management guidelines for: *Establishment of management zones (use areas) *Permit system and fee structure for overnight use ...

Drowning
Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance. After successful resuscitation, drowning victims may experience breathing problems, vomiting, confusion, or unconsciousness. Occasionally, victims may not begin experiencing these symptoms until several hours after they are rescued. An incident of drowning can also cause further complications for victims due to low body temperature, aspiration of vomit, or acute respiratory distress syndrome (respiratory failure from lung inflammation.). Drowning is more likely to happen when spending extended periods of time near large bodies of water. Risk factors for drowning include alcohol use, drug use, epilepsy, minimal swim training or a complete lack of training, and, in the case of children, a lack of supervision. Common drowning ...

Physical Trauma
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a person ...

Dehydration
In physiology, dehydration is a lack of total body water, with an accompanying disruption of metabolic processes. It occurs when free water loss exceeds free water intake, usually due to exercise, disease, or high environmental temperature. 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 ten percent of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs at a loss of between fifteen and twenty-five percent of the body water.Ashcroft F, Life Without Water in Life at the Extremes. Berkeley and Los Angeles, 2000, 134-138. Mild dehydration is characterized by thirst and general discomfort and is usually resolved with oral rehydration. Dehydration can cause hypernatremia (high levels of sodium ...

Black Suspension Bridge
The Black Suspension Bridge (also known as the Kaibab Trail Suspension Bridge) spans the Colorado River in the inner canyon of Grand Canyon National Park. The span length is . The bridge is part of the South Kaibab Trail and is the river crossing used by mules going to Phantom Ranch. The Black Bridge and Silver Bridge, located about downstream, are the only spans in hundreds of river miles. History Before 1907, the only way to cross the river was by boat, a dangerous method which cost many lives. Then, outdoorsman David Rust built a privately-operated cableway. The cableway was a steel cage large enough for one mule or several people that would carry passengers across the river, but the passage was considered precarious. Theodore Roosevelt used the cableway in 1913. The second crossing was a suspension bridge that lacked stiffness. It was built in 1920 and proved to be too flexible to safely carry pedestrians across the river as the number of visitors to the park was increasing. ...

Phantom Ranch
Phantom Ranch is a lodge inside Grand Canyon National Park in Arizona. It sits at the bottom of Grand Canyon, on the east side of Bright Angel Creek, a little over half a mile north of the Creek's confluence with the Colorado River. Opened in 1922, Phantom Ranch is a member of Historic Hotels of America, the official program of the National Trust for Historic Preservation. History The site of Phantom Ranch and the areas around it were used by various Native American peoples for millennia. Numerous artifacts, including split-twig figurines carbon dated at 4000 years old, have been discovered in nearby caves. Puebloan peoples built pit houses and a ceremonial kiva in the area around AD 1050, and likely survived by hunting and growing corn, beans, and squash. Paiute and Havasupai people also inhabited Grand Canyon for many centuries and probably visited the area, although no direct evidence of this has yet been discovered. The earliest recorded visit by European Americans took place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
