how many miles can i see from top of a mountain
The map above shows how far you theoretically could see from the top of Mt. Everest on perfectly clear day, with perfect vision and without any obstacles. And the answer, in case the text above is too small, is 340km (211 miles) in any direction. This would cover a total area of 363,000 sq km (140,000 sq mi), where you could see things, roughly the same size as Germany, Japan or the sate of Montana.
