1) Let’s begin with the good news. There was once a wedding on the summit of Mount Everest. Moni Mule Pati and Pem Dorjee Sherpa from
Nepal were climbing the Everest with Rotary Centennial Everest Expedition in 2004 and got married on the top. They kept their plans a secret until the top.
2) Traffic jam in Mount Everest is a normal phenomenon. On May 19, 2012, there was a crowd of climbers near the summit with a two hour wait. A total of 234 climbers managed to reach the peak but four died.
3) Babu Chiri Sherpa has the record for the person staying the longest on the summit in 1999. He stayed for 21 hours under the open sky at an elevation of 8828 meters.
4) The fastest ascent was made by Pemba Dorje Sherpa from Everest base camp to the top. He made it in just eight hours and 10 minutes.
5) Bear Grylls, who at 23 became the youngest British climber to summit Everest in 1998, was also the first man to fly higher than the top of the world in a powered paraglide - a feat he achieved in 2007.
6) A Swiss attempt to climb Everest in 1952 failed by just 250 meters hampered by malfunctioning oxygen canisters. The British expedition the following year learned from that experience; and accordingly, changed their route for their attempt at summiting.
7) A recent study led by a Nepalese scientist suggested that glaciers around Mount Everest have shrunk by 13 percent in the last 50 years. The snow line is also thought to be 180 meters higher than it was in 1963. The study was conducted through the University of Milan.
8) Reinhold Messner was the first to climb the mountain without oxygen, along with Peter Habeler, in 1978. Two years later, Messner surpassed the achievement, reaching the summit solo – again without bottled oxygen.
9) In 1856, the mountain was named after George Everest, a retired Surveyor General who never even saw the peak.
10) Peter Hillary, Sir Edmund Hillary's son, climbed the mountain in 1990, making the pair the first father and son to do so.
11) The Trigonometric Survey of India in the 1850s confirmed Everest’s existence.
12) The Indian mathematician, Radhanath Sikdar, was the first to put a figure on the height of the mountain. He calculated that it reached 29,002 feet (now adjusted to 29,035 feet), the highest point ever recorded on earth.
13) The first flight over Everest took place in April, 1933. Douglas Douglas-Hamilton and fellow pilot David Fowler MacIntyre flew a Westland PV-3 biplane over the summit.
14) Eighty years later, Douglas’s grandson Charles Douglas-Hamilton flew to the peak as a passenger in a Jetstream 41 Turboprop.
15) The mountain has even been skied down. On October 7, 2000, a 38-year-old Slovenian, Davorin Karnicar, skied 12,000 feet back to the south-side Base Camp.
16) The first two men to snowboard down Everest were the Frenchman Marco Siffredi and Austrian Stefan Gatt in May, 2001. In September, 2002, Mr. Siffredi attempted to descend the mountain a second time, choosing the steepest and most hazardous route. However, this proved to be a challenge too far, and he disappeared midway through the descent.
17) In May, 2005, Didier Delsalle claimed to be the first helicopter pilot to land on the summit of Everest. Delsalle’s unmodified helicopter hovered while making contact with the summit for around two minutes.
18) The worst year on Everest, in terms of deaths, was 1996 when 15 climbers died in the season, including nine in a single incident (documented in Jon Krakauer's book, 'Into Thin Air'). A close second was as recently as 2012, when 11 climbers lost their lives. Hundreds of corpses are thought to still be on the mountain.
19) The most dangerous area of the mountain is often considered to be the Khumbu Ice Fall, which is particularly dangerous due to the unpredictable movement of the icefall.
20) The oldest person to climb Everest is 80 year-old Yuichiro Miura of Japan.
21) Yiuchio Miura also successfully skied down nearly 4,200 vertical feet of the mountain (although not the whole way) from the South Col. A documentary, The Man Who Skied Down Everest, was the first sports film to win an Academy Award for best documentary in 1975.
22) The mountain has many names. In Nepal, the mountain is known as Sagarmatha, meaning “forehead of the sky” and in Tibet it is knowns as Chomolangma or “mother of the universe.”
23) The youngest person to reach the summit is 13 year old Jordan Romero. In May 2010, the young American broke the record previously held by 15 year old Ming Kipa of Nepal.
24) In 2010, Dubai broke the record for both the world’s tallest building and tallest man-made structure of any kind with the Burj Khalifa at 829m high. Everest is more than ten times its height.
25) The world’s second highest building, Taipei 101 in Taiwan, which held the record between 2004 and 2010 at 509 meters, would need to be stacked up more than 17 times over to reach the peak of Everest.
26) It normally takes around 12 hours to climb the final mile from the highest Base Camp to the summit.
27) Lhakpa Tenzing Sherpa currently holds the record for the highest number of successful ascents, having climbed Everest 21 times since 1990.
28) The British record is held by Kenton Cool who has now climbed to the summit of Everest 11 times.
29) The temperature at the summit never rises above freezing, averaging -32F (-36C) in winter and -2F (-19C) in summer.
30) Last May, a local Nepalese woman, Churim Sherpa, was the first to complete back-to-back climbs to the summit in the same climbing season. She made the first ascent with a group of four other mountaineers on May 12 2012. Then, five days later and with just two days’ rest, she went up Everest for a second time, climbing solo and tackling the mountain’s steepest face.
31) The first tweet from the summit was sent by Kenton Cool in 2011. On one of his many trips to the top, he tweeted: "Everest summit no 9! 1st tweet from the top of the world thanks to a weak 3G signal”
32) Leanna Shuttleworth became the youngest British woman to scale the heights of Everest when she climbed to the summit at age 19 in 2012.
33) Every year the mountain grows taller by 4mm as a result of the upward thrust generated by two opposing tectonic plates.
34) The rock at the summit of Everest is marine limestone and would have been deposited on the seafloor around 450 million years ago.
35) Even after Sir Edmund Hillary and Tenzing Norgay had reached the summit, Everest’s West Ridge was widely thought to be unclimbable. However, in 1963 two Americans, Willie Unsoeld and Tom Hornbein, proved otherwise when they reached the summit using this route. It still has a fearsome record. More people have died trying to reach the summit this way than have succeeded. Charles Wylie, a member of the 1953 British expedition called it "the most remarkable feat I have heard of in high-altitude mountaineering."
36) Unsurprisingly, some of the highest ever mountain rescues have taken place on Everest. Perhaps most notable was a 2001 rescue, when a guide and another climber were rescued after spending the night at 28,500 feet.
37) In 2006, Sir Edmund Hillary criticized climbers who failed to rescue a Briton, David Sharp. Mr Sharp, a 34-year-old, died on the mountain.
38) George Mallory and Andrew Irvine were known to have carried Kodak camera with them on their ill-fated attempt on the mountain in 1924. Some believe that they reached the summit. The only way that could be proved would be if the camera were ever found. The recent attempts to find Irvine's body have been criticized by his relatives.
39) Towards the top of Everest, people take in approximately a third of the amount of oxygen that they do at sea level. It’s not that the composition of the air changes - it’s just that the air pressure reduces significantly, meaning less can be absorbed into the system.
40) In a recent interview, Reinhold Messner caused controversy when he said that up to 90 percent of those passing through Everest base camp could be using chemical assistance to climb the world's highest peak.
41) News of the first Everest ascent reached Britain on the eve of the Coronation.
42) An Indian woman who lost her leg after she was thrown from a moving train two years ago has become the first female amputee to climb Everest.
43) Everest has now even been mapped by Google, although it did not get to the summit. In 2011, a team spent 12 days walking more than 70 miles to reach Everest base camp to capture images for Google maps.
44) Edmund Hillary escaped the media attention at a house in Norfolk after his successful climb of the mountain. He stayed at his sister’s house in Norwich in July, 1953 after his descent.
45) Both the oldest man and woman to climb the mountain are Japanese. A 73-year-old Japanese woman became the oldest female to scale Mount Everest, breaking the record she set a decade ago. Tamae Watanabe, a retired office worker who lives at the foot of Mount Fuji, Japan's tallest mountain, led a team of four on the assault on the northern face of Everest in 2012. See fact 14 for details of the oldest man.
46) Eight ton of rubbish collected from the slopes of Everest - including the remains of a helicopter - were turned into works of art and sculpture to highlight the issue of littering on its slopes. It took 65 porters and 75 yaks to carry down the rubbish from the mountain over two spring expeditions.
47) Josh Lewsey, who was in England’s 2003 World Cup winning rugby squad, has narrowly failed to climb the world's highest mountain, after faulty oxygen equipment stopped his ascent.
48) In the first ascent, Hillary reached the summit first, as Tenzing admitted in an autobiography as early as 1955. But since Hillary insisted that the matter was of no importance, and that the achievement belonged equally to them both, he refused for years to claim any primacy - even when the King of Nepal announced that Tenzing had been on the summit before him.
49) The summit of Mount Everest is only just lower than the cruising altitude of a jumbo jet. Most commercial aircraft tend to fly at between 30,000 and 36,000 feet.
50) There are two main routes to the summit: the south-east ridge from Nepal and the north ridge from Tibet.
51) The Nepalese call it Sagarmatha, meaning "Forehead (or Goddess) of the Sky". In Tibet it is known as Chomolungma, "Mother Goddess of the Universe".
52) The first woman to climb Everest was Junko Tabei, from Japan, in 1975.
53) Avalanches are the foremost cause of death, followed by falls.
54) The first blind person to reach the summit was the American, Erik Weihenmayer, in 2001.
55) A 1976 U.S. study concluded that Sherpas had undergone genetic adaptations after living in one of the world's highest regions for thousands of years.
56) More than 33,000 feet of fixed rope is used every year to set the South Col route.
57) The largest group to climb Everest was a 410-member Chinese team, in 1975.
58) Although Mount Everest is the highest mountain above sea level, Hawaii's Mauna Kea is the tallest mountain base to peak, measuring a total of 33,500ft; only 13,796ft of which is above sea level.
59) In May of 2006, the New Zealander, Mark Inglis, became the first double amputee to reach the summit. During the ascent, he broke one of his prosthetic legs. Adhesive tape temporarily repaired it while a spare was brought up from base camp.
60) The country that has lost the most people to the mountain is Nepal.
61) Sherpa is the name of a group of nomadic people in eastern Nepal, who also use it as their last name. Usually, their first name is the day of the week on which they were born.
62) In October, 1950, expeditions from the north were prohibited after Tibet was invaded by China. The same year, Nepal opened up access to Everest's south side.
63) Davo Karnicar from Slovenia was the first person to ski down Everest in July, 2000.
64) Sherpas suffer altitude sickness like everyone else.
65) In 1953, Sir Edmund Hillary and Tenzing Norgay reported seeing large footprints while ascending. Hillary later discounted Yeti reports as unreliable.
66) No one knew that Everest was the tallest mountain in the world until 1856, when the Great Trigonometric Survey of India established its height.
67) The only climber to scale all four sides of Everest is Kushang Sherpa, an instructor with the Himalayan Mountaineering Institute.
68) In October of 1978, Wanda Rutkiewicz became the first Polish person to summit – the same day as fellow Polish, John Paul II, was named as Pope.
69) It is estimated that expeditions to climb the mountain take two months from start to end.
70) Geologically speaking, Mt Everest is about 60 million years old.
71) The best places to see Mount Everest up close would be a trek up to Kala Pathar or to Gokyo.
72) The height of Mount Everest depends on what side of the border you’re on. China has claimed the peak is at 8,844 meters (29,016 ft), while Nepal says 8,848 meters (29,029 ft).
73) Everest is turning to be dirty day by day cause The slopes are strewn with discarded oxygen bottles, climbing equipment, and plenty of human feces.
