Baby, itís cold outside! Iíve strapped metal spikes to my boots so I could make the four-hour climb up Franz Joseph, the biggest commissionable glacier in the world. I felt like a bad ass hiking on this monstrous block of ice. That is, until I almost froze mine off after my pants got wet on melting, icy walls while slipping through extremely narrow crevasses.
But the really cool thing is that I got to see that glaciers are bright blue as well as snowy white. My guide said itís caused by light refracting through trapped air pockets. And thatís my science lesson for today.
