Another scale example - but how do you show this well?

Following on from Stubbsy's "Importance of Scale" post from Rotorua's Redwood Forest, I thought I'd share this one - and pose the question of how the heck you really show these glaciers in a way that brings their true size to life...
Fox Glacier (we got a good view of it for half an hour or so before it clouded back in!)...
Franz Josef as clear as we got it - note the top of it dissappearing into the clouds...
See the ice cave at the base of Franz Josef? Now take a closer look - here's the scale bit I'm talking about...
And so I ask the question again - how the heck you really show these glaciers in a way that brings their true size to life?
