Blue Ice

Portage Glacier, Alaska

This was the actual color of the ice spires! I was in awe.

Why is Glacier Ice blue?
Starting out as a mixture of ice & snow, some Glacial ice has been compacted so tightly - over thousands of years - that eventually only blue (a high energy color) will remain the only color to still be reflected back. Other colors (that would normally appear white) are filtered out. The older and more tightly compacted the glacial ice, the bluer it will look. Glaciers and glacial ice will also appear even bluer on cloudy or low light days.

Liz not as pretty as it was back in the late 60's. I remember the big pieces of ice floating in the little lake that was at the bottom. The water and ice were sky blue and the water as clear as a mirror.
But your photo does show how the years of subsiding has taken away from the actual glacier.
