40 years ago, I was briefing an explorer re possible ice conditions in Bering Strait for a trip he was planning. One danger he mentioned was, when peeing in really cold weather, a stalagmite can form rapidly and, if you don't change your angle of dangle, you may find yourself anchored.
Another polar explorer from that same era, Wally Herbert, was asked by a reporter, "how do you go to the toilet in the Arctic?" Wally replied, "very quickly!"
