Tracy Arm-Fords Terror Wilderness – Image 2452

Glacier blue ice provides one of nature’s most vivid color displays. Snowflakes or snow crystals become glacier ice when compressed under the weight of continuous snowfalls over hundreds of years. The massive weight of the ice pushes out any tiny air pockets between the crystals, producing an extremely dense, clear, air-free ice. This ice absorbs all the colors of the light spectrum except blue which is reflected off the ice giving it the intense blue color.
