This is a very large (17,000 x 8,500 pixel) composite photomosaic map of East Angmar, from Garth Fornir to Carn Dum and Urugarth inclusive. It is in the form of a 32.5 MB JPEG file; once downloaded, it can be overwritten, printed, viewed onscreen and so forth.
You can download it from this link: http://rapidshare.com/files/140723301/Carn_Dum.jpg. Even if you don't have a Rapidshare account, it can be downloaded for free after a 30-second wait. Personally, I found it very helpful both for navigating and as a way of getting a sense of how the various parts of this very complex area relate to one another.
