About 60 million years ago, an area of land stretched out into the Indian Ocean. This area slowly drifted inland over tens of thousands of years and pushed its way upward into ridges and folds of rock. This marvelously rocky region became a mountain range we now call the Himalayas. The Himalayas are located on the continent of Asia. The highest mountain in the Himalayas, Mount Everest, climbs high into the sky. This natural wonder has become a popular destination for climbers and tourists seeking adventure and spectacular sights.
I work as a tour guide here at the mountain. Climbers sometimes hire me to guide them to the summit. I know all there is to know about Everest. First of all, it is the highest mountain on Earth. In 1979, the area surrounding Everest was designated as a natural world heritage site. It sits on the border between Nepal and Tibet, which is a region of China. In fact, the border runs right up over the peak of the mountain. The summit of Everest soars high above the clouds at an astonishing 29,029 feet. That's almost as high as airplanes fly! On the summit of Everest, climbers stand as close to the stars as they can with both feet still on Earth. I have stood on the breathtaking summit myself almost a dozen times. The feeling is unbelievable, so it is no wonder this towering mountain has attracted climbers for centuries.
