Where it s snow covered, the Athabasca Glacier is white, but its edges and deep crevasses reveal the real color of the ice. Formed under intense pressure, glacier ice has little air in it and the light that would normally be reflected by air bubbles instead penetrates deep into the ice, where it is largely absorbed.
