Cravasses and the medial moraine on Ruth glacier
The blue-tinted cracks are deep cravasses in the glacier. Cravasses form in quicker-moving areas of a glacier. Glaciers form when snow builds up faster than it can melt. Over time the snow compresses forcing the air out, creating very clear ice. This ice absorbs all the colors of the spectrum except blue which is reflected giving the glacier its beautiful blue hue.
