No such luck, Charlie.
Brian Reid, who owns and supports the Leica Users Group site, gave the
best suggestion. It's really about the physics of freezing of a
contained liquid. He suggests that the surface of the bird bath froze,
trapping the liquid below. When it continued to freeze, the expanding
slush found a weak spot in the ice and pushed upward. To me, it is
similar to what I recall when milk was delivered in glass bottles. In
freezing weather, the freezing milk on the front porch would push out
the cardboard cap and lift it on a column of frozen milk.
By the way, there is a smaller one this morning, on the opposite side of
the bird bath.

Last night the temperature got down into the 20s F. This morning, I
glanced out at a bird bath that stands in a clear area of the yard, with
nothing above it. The water in the bird bath appeared frozen, as I
would expect, but a clear icicle was standing about eight inches tall.
What caused this?

I'm sure someone must have the answer.
