Very interesting and actually factual facts..Rare indeed.
In Wales, any height over 1,000 feet is considered a mountain, and the highest mountain in the country is Yr Wyddfa (Mt. Snowdon) at 3,560 feet (1,085 metres). Those who watch Hollywood movies may remember The Englishman who went up a hill and Came Down a Mountain, starring Hugh Grant and Tara Fitzgerald. This height may seem minuscule compared to the massive elevations of the Himalayas, and yet it was in Snowdonia, with its barren, precipitous rock faces, that the British members of the first team to conquer Everest in 1953 did much of their training. Just south of the Pass of Llanberis, you will find the Pen y Gwryd Hotel in which some mementos of the 1953 team are kept.
Mt. Everest is known in the Tibetan language as Chomolungma, "Goddess Mother of the World." It was recognized as the highest point on earth in 1852 following a government survey of India when the awesome mountain was named Peak XV. It became Mt. Everest in 1865, named for Sir George Everest, surveyor general of India, a native of Gwernvale, Breconshire, Wales, who had conducted the first triangulation survey of central India. Everest introduced the most accurate instruments of the day to complete his measurements and calculations with great precision. In 1955, the height of Everest was established at 29,028 feet.(Britannia Online)
