Why is Glacier Ice Blue?

Glacial ice is a different color than regular ice. It is so blue because the dense ice of the glacier absorbs every other color of the spectrum except blue--so blue is what we see!

It's Not Frozen Water!
Sometimes the glacial ice appears almost turquoise. Its crystalline structure strongly scatters blue light. The ice on a glacier has been there for a really long time and has been compacted down so that its structure is pretty different than the ice you normally see. Glacial ice is a lot different than the frozen water you get out of the freezer.

It's Not Frozen Snow!
Glacial ice is not just frozen compacted snow. There are other things in the ice that make it much different than the ice in your home. Glaciers move through rock and soil as they carve their way down a slope. This means the ice is going to have a lot more ingredients than just water.
