On this rare good weather day. I was able to capture this unique glacier and it’s also the world's largest non-arctic glaciers, Malaspina. What causes the dizzying pattern of curves, zigzags, and loops of moraines? Glaciers in this area of Alaska periodically “surge,”meaning they lurch forward quickly for one to several years. As a result of this irregular flow, the moraines at the edges and between glaciers can become folded, compressed, and sheared to form the characteristic loops seen on the glacier.
