from above, but at only maybe 28-32 degrees, it would not freeze right away like in the arctic (and no icicles here at those temps, snow only lasts a few hours here)--oh, and the water below it was not frozen... Very strange. Very odd sharp edges at the bottom, and it was maybe 6" high. So odd. (I keep editing this for clarity...like it matters...)

Landed heavy side (icicles are thicker at the top) down, punching a hole through the ice layer already formed in the bowl. The ice was thick enough to not shatter across the surface, and the icicle was thick enough to penetrate the ice layer without shattering. The resulting hole was wider than the circumference of the upside down icicle, so that when it came to rest, it did so at an angle..

Or it was in fact aliens..

....so I went looking. What I found. There is a picture at the website, but I can't post it.

Ice spikes grow as the water turns to ice. Water expands by nine per cent as it freezes. The ice slowly freezes in from the edges, until a small hole is left unfrozen in the surface. Since ice expands as it freezes, the ice freezing below the surface starts to push water up through the hole. If the conditions are just right, the water will be forced out of the hole and it will freeze into an ice spike. With time, as water continues to come up through the hole, it freezes around the bottom and the spike continues to get longer or taller.
