In reply to tspoon1981:
It is a TV news report; they're not renowned for their accuracy.
Why assume that 'Mount Dubh' is 'Ben Macdui'?
Why not get some basic position information from the mobile phone network? You may not be able to triangulate, by the identity of the base station actually connecting with the caller at least, would have distinguished between Glencoe and the Cairngorms.
