Margerie Glacier is accessible only via boat. It's in Glacier Bay in Alaska and it glows blue on cloudy days. Seven feet of solid ice calve off every day - that's how fast it moves. It was raining when I made this image from the deck of our boat. The color, texture, contrast, detail and geometry are amazing. Luckily it was overcast because the blue really pops.
We were lucky enough to see a ton of ice calve off the glacier that day. It's like lightning striking when it cracks off and thunders when it hits the ocean surface.
