How tall is Mt. Everest, the world's tallest mountain? That's what Nepal and China—the two Asian nations that Everest straddles—want to know. Nepal says the mountain is 29,028 feet (8,448 meters) high. China says that number is wrong. The Chinese claim Nepal's figure is about 13 feet (4 meters) too high. (Meanwhile, some climbers think Nepal's estimate is too low!)
In order to settle the argument, Nepal plans to take a new measurement of Mount Everest. Everest has been measured several times since it was first sized up in 1856. But this one may be the most scientific of all.
"We have begun the measurement to clear the confusion. Now we have the technology and the resources, we can measure ourselves," said Gopal Giri, a spokesman for Nepal's Land Reforms Ministry. "This will be the first time the Nepal government has taken the mountain's height."
Nepalese officials will set up three reference points on the mountain and use global-positioning satellites to calculate the exact height. This process could take up to two years.
