A while back, I read a geoscience paper about those stone arches that form out of sandstone in the american southwest, and what the mechanism is behind them. Basically what happens is that the wind scours certain areas of vertical faces of stone, and as they wear away, the stone crystals directly above the worn areas are put under stress and begin to compact. This compaction actually makes them harder and more resilient to wear. Over time, the center is hollowed out below that initial compaction point and a natural arch forms.
I suspect something similar has happened here. The snowman started to slowly lean over, which put the snow crystals on the downward side under compaction, probably at just the right moment in the freeze/thaw cycle. So when it hardened up overnight, a strong arch of ice was formed. And the base is not only heavy but frozen to the ground to a sufficient degree to hold the whole thing more or less in place.
All in all, it's really cool! Thanks for sharing.
