It's hard to say which is encroaching at this point,
the water upon the ice, or the ice upon the water.
But they do not encroach — they are the same thing.
Surely one advances and the other recedes?
Surely an angel touches the waters till they are troubled?
No such luck: it all comes from up here and goes out here,
Some of it stays for awhile. Next era things will be different, maybe.
