I have to say, this is borderline pointless.
Firstly, most of the detail is of relatively uninteresting bits of snow, rock, and ice: there's no real motivation to zooming in and poking around, as there is in a similar multi-gigapixel panorama of a city, for example.
As someone said above, the real grandeur of the scene comes in taking in the wider view, at which point the whole hi-res aspect is totally moot.
Plus the mosaic making sucks. Really, right from the get-go, the repeated features in the foreground snowfield are utterly distracting, followed by blurring in many areas when you zoom in a little.
Admittedly, such things are extremely difficult to do well / right (I know from experience), but I've seen plenty of other panoramas which are far better in post-processing.
Ultimately, the question becomes: why bother? Oh, because it's "the most pixelliferous image ever taken". Sigh.
