Franz Josef Glacier Hike 4, FJ, NZ

I mentioned the dirt on the ice in a previous post... but even more interesting to me was the blue ice!

Apparently, all ice is naturally blue. ...But when exposed to sunlight, the ice loses its blue coloring and looks white. The blue ice that we saw on the glacier hike was recently exposed... or hidden within a cave-like hole to keep the coloring... very cool...

Bright blue inside the cave of ice! (And currently melting...)

Bright blue within the crevice...
