Well, have you edited anything around that place? Keep in mind that Noggit saves also all ADTs which are next to ADTs you have edited. You also could have somehow edited some model which is used there and your new version of that model causes you crashes. Trying to find out which particular ADT gives you crashes would be a great start.
Sadly, I tryed to go there in my Noggit and I get crash as well, and I've never edited a single ADT in whole Northrend. Error log:
84845 - (MapTile.cpp:53): Opening tile 27, 24 ("WorldMapsNorthrendNorthrend_27_24.adt") from MPQ.
88228 - (errorHandling.h:64): [Error] There was an exception of type "SIGSEGV"
"Invalid storage access; most frequently caused by attempting to store some value in an object pointed to by a bad pointer. (Segment violation.)".
Please excuse the inconvenience. You may want to report this error including the log to the developers.
I have no idea what can be causing this. You may try to get whole list of models (I would start with WMOs) used on that ADT and try to spawn them in Noggit in some test zone, to make sure Noggit doesn't crash with any of them. If it does, well, at least you will find out which model is causing it. Then you can discuss "fixing" it with other modders here. You may also find out that all models on that ADT work, well, that would be quite nasty and trying to find out solution with Noggit developers would be probably the only way, because that would mean, that Noggit can't open for some reason that particular blizzlike ADT because of... something.
