In reply to Björn Pohl - UKC:
Seems like you need a German here in the forum to clarify things.
1. Yes, it is a pun with "Dances with Wolves"
2. Der = male form and can be translated with "(he) who" or "the one who" if you wanna do it literally, so björn is right. It refers to Martin ie the climber in this context, not to the rock.
2. "Fels" simply is the material, nothing else. Everything from a small pebble to a big cliff is made of "Fels"
