I have seen things like this appear once or twice on cold winter mornings, a frozen spike of water from an ice-covered container or very small body of water (puddle).
I found the photo below at Mel Bartels and BBAstroDesigns and the caption reads:

What could be happening here? How might the two structures form like this, both tilted against gravity?
update: Comments indicate that Wikipedia's article Ice spike gives an explanation based on the growth of a tube as the freezing process extends from top-down into the liquid, pushing remaining liquid out a hole and growing vertically from a central opening in the tube.
However, I can't see how this makes a spike with such a large angle with respect to vertical. It really looks to my untrained eye like this is a frozen jet, but that's not so likely as water is not so compressible.
