The Steel Glacier is undergoing the most vigorous surge:
|On the upper glacier, the ice surface has dropped be several tens of meters, leaving behind a "bathtub ring" of stranded ice.|
|The fast flow creates very crevassed shear margins|
The Walsh Glacier is also surging. I think it's in its third year of surging now, but this is by far the most active I've seen it:
And finally a picture of Fisher Glacier. This surge might be done; it reached all the way to the glacier front.
