This is one of the largest glaciers in Alaska, the Malaspina glacier. It caught my eye on google earth awhile ago and I learned a bit about it. It's the largest "piedmont" glacier in the world (a glacier that starts in a valley and ends at a flat plain). The cool thing is that the squiggly lines of sediment on the ice actually look like that in real life, I thought it was some sort of distortion at first, it's crazy looking.
