I hate to necro a thread but this type of mountain looks interesting. I do have some questions for the author:

1) Is this something you setup prior to mapping (a la CC3) or,

2) something you add to an already existing map?

3) Can you make this a pattern somehow to utilize LIKE CC3 in order to cut down the time involved in placing the mountains (such as using the stamp tool)?

I am not one for taking shortcuts but my map is really big and it would be a big help if I could cut down the time even a little bit.
