Introduction to Red Glacier: Red Glacier is located in Red Inner Bay. Rednery Bay is the passageway for Glacier Bay National Park to enter and exit the Pan-Pacific Glacier and Margery Glacier. Due to the differences in the accumulation and density of the glaciers, among the cut ice sculptures, you can see that the ice does not only have one color, but also a variety of colors. All kinds of blue add a mysterious color to the misty fog.
