It always irks me when 'Mount' is added as a prefix to a proper mountain name like 'Mount Annapurna', 'Mount Ama Dablam'. Should it then be 'Mount Mt. Everest'?
This occurs with all geographical features whenever a name crosses into another language whose speakers can't interpret the part of the name that means "river" / "mountain" / "fort" / "bridge" / "hills" / "vale" / etc.
