Looking at Wikipedia I can follow your point. But I think this is more due
the language links. I think "ridge" is the common term which encompasses
both German terms "Grat" and "Gebirgskamm". Here some articles from
Wikipedia that should show their common use:
* http://en.wikipedia.org/wiki/Crib_Goch - especially legend of map
* http://en.wikipedia.org/wiki/Mount_Everest#Southeast_ridge

Also interesting is the definition of Arête as a kind of ridge in
Merriam-Webster: http://www.merriam-webster.com/dictionary/arete

Is this all the same? Shall we distinct between them?

Basically I think we shouldn't.

This would definetly help - especially for us Germans trying to understand
the difference :-) Here a picture of what I personally would consider a
ridge: http://upload.wikimedia.org/wikipedia/commons/d/d6/Herzogstand_HQ.jpg
