Next time you visit Winterhold or the Mages Guild have a walk around the area. There is loads of available space. It also has horse carriage travel from all the other cities already written in the game.
Yeah sure I'll just walk around the colle... wait a minute. Oh that's right. There's nothing to walk on

But if you are referring to all the glaciers... that'd be nigh impossible. But I'll take a gander up in the wastes to see. If nothing else, it'd give me a reason to venture up there. By God I hate Winterhold.
