The Yeti has regularly been sighted since 1832 when it was first spotted in Nepal by BH Hodgson.

The first reliable report of the Yeti appeared in 1925 when a Greek photographer, N. A. Tombazi, working as a member of a British geological expedition in the Himalayas, saw a creature moving in the distance across some lower slopes. The creature was almost a thousand feet away in a area with an altitude of 15,000 feet. "Unquestionably, the figure in outline was exactly like a human being, walking upright and stopping occasionally to uproot or pull at some dwarf rhododendron bushes," said Tombazi, "It showed up dark against the snow and, as far as I could make out wore no clothes." The creature disappeared before Tombazi could take a photograph and was not seen again. The group was descending, though, and the photographer went out of his way to see the ground were he had spotted the creature. Tombazi found footprints in the snow. "They were similar in shape to those of a man, but only six to seven inches long by four inches wide at the broadest part of the foot. The marks of five distinct toes and the instep were perfectly clear, but the trace of the heel was indistinct..." There were 15 prints to be found. Each was one and one half to two feet apart. Then Tombazi lost the trail in thick brush. When the locals were asked to name the beast he'd seen they told him it was a "Kanchenjunga demon." Tombazi didn't think he'd seen a demon, but he couldn't figure out what the creature was either.

One of the more curious reports of a close encounter with a Yeti occurred in 1938. Captain d'Auvergue, the curator of the Victoria Memorial in Calcutta, India, was traveling the Himalayas by himself when he became snowblind. As he neared death from exposure he was rescued by a nine foot tall Yeti that nursed him back to health until d'Auvergue was able to return home by himself.

In 1951, an expedition found a track on the southwestern slopes of the Menlung Glacier between Tibet and Nepal, at an altitude of 6000 meters. The footprints they saw were 33 cm by 45 cm and were made by a foot which has 5 toes of which the inner toes were larger than the others. The heel was flat and exceptionally broad. The track itself appeared to be fresh so the footprints were not enlarged by melting snow. Eric Shipton and Micheal Ward, two British mountaineers followed the trail for a mile before it disappeared in hard ice. This was clearly shown by the many photographs they took. Although there were many doubts about these photographs, if they were believed to be true at all.

The London Daily Mail sent an expedition in 1954, american oil men Tom Slick and F. Kirk Johnson financed trips in 1957, 58, and 59. In 1959, Yeti droppings were recovered and brought for further investigation. A new species of nematode worm was discovered, which according to scientists, will only be found to be linked to one type of animal. As this species of worm is known not to be linked to any other animal this evidence has been accepted as proof towards the yeti existing.

Sir Edmund Hillary, the same man that had first climbed Everest in 1953, has alleged to have come into contact with the yeti on several occasions. On their record ascent to the top of Mount Everest,he and his Sherpa guide, Tenzing Norgay, found giant foot prints on the way up. In 1960 Sir Edmund with Desmond Doig, led an expedition sponsored by the World Book Encyclopedia and well outfitted with trip-wire cameras, as well as timelapse and infrared photography. Unfortunately, his expedition was as unsuccessful as those who had gone before. Despite a ten-month stay the group failed to find any convincing evidence of the existence of the Yeti. However, he brought back with him two skins and a scalp which he claims to be the upper half of the skull of a Yeti. This scalp came from the Khumjung Gompa (monastery) in Nepal where it is kept as a relic. It is some 300 years old, 20 cm high and has a circumference of 65 cm. But Scientists said it belonged to a serow (mountain goat) which lives in eastern Asia and two blue bears.

In 1972 footprints were found by Edward Cronin and Dr Howard Emery on an expedition in Nepal. The footprints were found amidst the base camp in a valley between Everest and Kanchenjunga, and followed a path from the camp to a steep incline. The expedition agreed that the incline was extremely treacherous and would be virtually impossible for a human to climb. A mould was taken of the footprint for future research by Jeffrey McNeely.

A yeti was alleged to have attacked Lhakpa Domani in 1974 near Mount Everest. She described it as similar to a large ape-like creature with black and brown hair. It was said to have picked her up and thrown her some distance, then attacked the yaks that she had been tending.Her brother found her soon after, wounded and unconscious, but alive. Several nearby Yaks lay dead, half eaten. The Yeti’s footprints were all around them. No reason whatsoever could be found for the unprovoked attack.
