Sno-Fall Ice is ice that falls as snow into water forming slush. It is occasionally formed on black ice, often after a big snow storm. This page looks at a range of different configurations and lays out some ideas about what brings on the different shape.
A lot of this is conjecture and I accept responsibility for any violation of the laws of physics.
The following are some pictures of snow-fall ice figures.

Late December 2020: A powerful Nor-easter dumped a lot of snow over southern Lake Champlain (14" or so). The light grey to darker grey reflects the amount of air bubbles in the interstitial space in the slush. It looks like the whiter shades. The wavyness of the seems to reflect more bubbles high on the vertical topography of the slush/water inteface.
The skaters here report that the ice was very smooth.
