I’ve never done this while winter camping, but while working one winter in New England installing thermal solar systems on roofs, we’d heat up the base of the aluminum ladder with our torches, letting it melt into any ice puddle and then refreeze, making it much more secure and less likely to blow down (there were still some times when Joe and I would be yelling to Jeff in the basement to come set the ladder up again – sometimes shouting into the chimney worked best).
But we have Bic lighters and camp stoves along, right? So we could heat a small screw or nail and melt it into a frozen puddle or lake if needed.
Mostly, don’t camp on solid ice – packed snow is softer, but in case you ever have to. . .
