Trying to get to Amon Thanc and Crookdell. I know Crookdell is on the west side of the area, but can't tell if it's on a mountain/hill or not. Amon Thanc is proving to be difficult - it looks like it's on top of the mountain in the center section of the area, but I can't find any way up to it.

Any and all help is greatly appreciated.
