text: According to other printed hiking maps and also personal experience, the northern slope of peak Καλλιφώνι is far more steeper than expressed here.
  To be more specific, there is a big couloir - gully (https://en.wikipedia.org/wiki/Couloir) right at the Northern face of this peak.
  I can not find any guidelines on how to correct this on the map... so I mention it here.
