KATHMANDU, June 29: Survey scientists involved in measuring the height of Mt. Everest have said that it might take nearly a year more to come up with a final figure. Although around 85 percent of work related to leveling surveys has been completed, surveyors say the remaining work is being halted for a few months because of the monsoon. The initial target of completing the survey work by December and finalizing the results will be delayed by a few months.The remaining work is to resume only after mid-December, it is stated.
