Can horses get snowblindness?
Yes.
What are the dangers of climbing MtEverest?
Aveleanch, frostbite,hypothermia, snowblindness,ams ,animals and death
How is photokeratitis caused?
by excess exposure to UV light. This can occur with sunlight, suntanning lamps, or a welding arc. It is called snowblindness because the sunlight is reflected off of the snow.
Is snow blindness more likely to occur on a sunny day or on a cloudy day?
It depends, but ultimately snowblindness would be more likely to occur on sunny days, This is because the snow reflects the sunlight into your eyes. It makes sense if there is higher intensity of sunlight being reflected on the snow, but sometimes if the clouds are thin enough, they would concentrate the sunlight, making it seem brighter. So it really depends.
How does Everest's temperature effect your body?
The temperature of the mountain itself does not have much of an effect. The air temperature and pressure will though. The low air pressure will make it difficult to breath, the suns radiation will be stronger (even if it doesn't feel hot) and sunburns are easy to get, sunglasses must be worn to avoid snowblindness and sunburned eyelids, weather changes can be extreme and sudden so extra clothes will be needed. There is a lot of information one should know before attempting a climb. You'd need to research and train extensively if you plan on surviving.
What might prevent a climber from getting to the top of mount Everest?
There are many reason why climbers dont survive on Mount Everest. Avalanches, rockfall, bad weather, illness, a fall, snowblindness are just a few reasons. For more take a look at the articles in the links I have given.
What are the dangers of climbing a mountain?
There are many threats encountered in mountain climbing, and any of them could increase exponentially with increased elevation (height of the mountain).Injury (or death) from a fall, including those caused by slips or by windInjury or suffocation from rocks, ice, or snow falling on youInjury from exertion (heart, muscles)Injuries from temperature extremes (mainly hypothermia and frostbite)Injuries related to breathing thinner air (heart, lungs, muscles, brain)Effects of untreated illnesses, or lack of medical careVision loss from glare (snowblindness)Lack of food (and on some mountains, water)Equipment-related injuriesDrowningAccidental, negligent, or intentional injury by other climbers- Some of the dangerous conditions are avalanches, rockfalls, earthquakes*, ice storms, dust storms, and flash floods. Physical effects can include frostbite, hypothermia, heat stroke, dehydration, and cramps. Storms can reduce climbing visibility, and bright sunshine can cause temporary snowblindness.- If a climber is trapped on a mountain, or lost, starvation is a possibility. Those taking medications may run out if a climb takes longer than anticipated.- At high elevations, altitude sickness can lead to lethargy, poor judgment, or disorientation.- Arguments, fights, or other actions that can be harmful anywhere else may be fatal on a mountain, where there is no immediate medical care. Decisions by a group leader may imperil everyone, or an individual may imperil other climbers dependent on him.This is not a complete list but encompasses most of the main dangers of mountaineering. Experienced climbers will usually have encountered most of them.(see related question)* In 2009, there was a Richter 6.1 earthquake at a Himalayan glacier called Satopanth while people were climbing the mountains around it.
What did Captain Robert Falcon Scott eat on his journey to the South Pole?
Sledging rations usually consisted of 12 ounces of pemmican -- 50/50 mix of lard and ground meat, 16 ounces of biscuits, 3 ounces of sugar, 2 ounces of butter, 0.7 ounces of tea, and 0.5 ounces of cocoa per man, per day. The most common meal they ate was called 'hoosh'. This could be made in several different ways, but the most common was to grind up pemmican and biscuits and cook it in hot water to make a thick, meaty stew. Scott and his men also relied heavily on tea. Tea was scarce on sledging journeys. When rations were tightened, lunch often consisted of tea and a biscuit. Used tea leaves were also discovered to be useful for relieving the pain of snowblindness (when the light of the sun reflected off the snow causes temporary blindness, usually lasting for several days).
What does it mean when your dogs eyes turn blue?
If you notice a bluish tinge to your dog's eyes that was not there previously, you should seek veterinary attention immediately. A bluish tinge to the globe can indicate increased pressure within the eyeball, which is glaucoma. Untreated, glaucoma is a very painful eye condition which can lead to blindness. Because it is often genetic, it often leads to blindness in both eyes. Dogs such as Cocker Spaniels, Shih Tzu and Chinies Shar-Pei are particularly prone to glaucoma. They should be screened for glaucoma on a yearly basis. The diagnostic test for glaucoma is a measuring of the pressure within the eyeball, done with an instrument called a tonometer. New tonometers are digital and provide quick, accurate results, but are very expensive, so may not be available in every practice. Be sure to ask your veterinarian if the office hasa tonometer before you have your dog's eyes checked. If the blue color is in the iris, or the colored ring around the pupil, it is probably a normal coloration of the iris, but be sure to have it checked out if it is something new.
Stories about a yeti?
Synopsis: In 1832, B.H. Hodgson, the British representative in Nepal, published an article about a strange mountain creature in a scientific journal. He described a hirsute creature who reportedly had attacked his servants. The natives called the beast "rakshas," which means "demon." This was the first report of the Yeti made by a Westerner. His told him that references to such wild men went back to the fourth century, BC. Hodgson had derided his servatns' talk of a demon creature and explained the intruder as a stray orangutan. It was fifty-seven years later in 1889 that Major L.A. Waddell of the Indian Army Medial Corps became the first European to see footprints made by one of the mountain monsters. The tracks were discovered 17000 feet up in northeast Sikkim. The next report was in 1913, when a group of Chinese hunters reportedly wounded and captured a hairy man-like creature, that the locals soon named the "snowman". This creature was supposedly kept captive in Patang at Sinkiang province for a period of five months until it died. It was described as having a black monkey-like face and large body covered with silvery yellow hair several inches long; it's hands and feet were man-like and the creature was incredibly strong. Remarkably, no evidence is present to substantiate this report. Forward to 1921, to the inevitable, alleged encounter of European and Yeti. Lieutenant-Colonel C.K. Howard-Bury had led the first Everest Reconnaissance Expedition. He and his team were climbing over a ridge at some 21000 feet, when one of his guides gripped his arm excitedly and pointed out a dark upright figure moving rapidly through the snow. On his return to his own country, Howard-Bury read up on the ways and customs of the Himalayan wild man, and learned that naughty Tibetan children are threatened into good behavior by warnings about the Yeti. "To escape from him, they must run down the hill, as then his long hair falls over his eyes and he is unable to see them." In 1925 a Greek/British photographer, N.A. Tombazi, observed one of these elusive creatures at 15000 feet up in the Zemu Glacier. His testimoney mentioned that the creature was "exactly like a human being, walking upright and stopping occasionally to uproot or pull some dwarf rhododendron bushes." Tombazi, later reached the spot where he sighted the creature, only to also find some intriguing tracks in the snow. Belief in the Yeti was growing from country to country, when in 1934, Maurice Wilson, theorized that they were mystical hermits, rather than wild beasts. This theory was also shared by the German missionary-doctor, Father Franz Eichinger. They were supposedly solitary monks who had withdrawn from the pressures of civilization and who lived in cold but contemplative peace in their mountain caves. Soon after, 1938 marked the point at which the Yeti became a creature of sympathy and kindness thanks to the story of Captain d'Auvergne. He claimed to have been injured while travelling on his own in the Himalayas, threatened with snowblindness and exposure. He was saved from death by a 9 foot tall Yeti. The giant picked him up, carried him several miles to a cave and fed and nursed him until he was able to make his way back home. And soon after, in 1942, the events from Slavomir Rawicz's book, The Long Walk (pub. 1952) had occured. He describes how he and his six friends escaped from a Siberian POW Camp and crossed the Himalayas to freedom in India. The book of course came under widespread attack as more fiction than fact, as there was the physical unlikeliness of surviving such a journey, including a 12-day hike across the Gobi desert with little food and water. Slavomir also described in his book, their encounter with two 8-foot-tall creatures near Bhutan and Sikkim. For two hours, he and his companions watched the creatures from 100 yards. The Daily Mail team in 1954 decided to organize its own expedition, and came up with a few hairs from a 300-year-old alleged Yeti scalp, kept in a Buddhist temple. The scalp, conical in shape, is about 8 inches high and has a base circumference of 26 inches. The hair was later analyzed and could not be attributed to any known animals. Even recent DNA testing of the found hair, defied analysis.
