Yes, it's really this blue
It was amazing, how blue the ice is. Also, how *loud* a glacier is. It was calving (breaking apart) all the time. Each time it did, it sounded like thunder, mixed with a gunshot. People kept wanting to photograph it when it was breaking apart, so they kept saying, "Do it again! Do it again!" at the glacier.
Meanwhile, I'm thinking, "NO! Don't!" while my mind is playing bits of "An Inconvenient Truth."
