To help clarify, could you please provide more context? For example:
* What do you mean by "unwrapped"? Do you mean mountains that have been eroded? Mountains with exposed rock layers? Or something else entirely?
* What kind of mountains are you interested in? Are you thinking about fold mountains, volcanic mountains, or something else?
* Do you have any specific examples in mind?
Once you provide more information, I can give you a more accurate and helpful answer.
