If/when you come to Alaska, take a helicopter jaunt if you can. You land on a glacier or two- everyone is issued a certain kind of bunny boot so you have good traction - and you can walk around peering into these pools of blue.

It's not something you easily forget.

And of course, as Rap says, you can see the blue in freshly 'cut' surfaces of glaciers.

However, Crater Lake in the Cascade range in southernish Oregon has almost the same blue. The first time I saw it, I just capered and hollered. I had always seen pictures of it but I think I thought that the color was lens-enhanced.

Glacier blue is more delicate than Crater Lake blue, actually. Glacier blue has almost a silver tinge to it.

Music and Glacier blue and Northern Lights- who can ask for anything more!
