Studies show the mountains of Venus may be covered in frost made of heavy metals. The planet is far to hot and with way too much acidic compounds in the atmosphere, and with a bit much pressure caused by the atmosphere to support frozen water. But the cool temps on the high mountain tops may be sporting frozen metal crystals.
Which is just bad ass. Space
Of course its just a theory. No one has gone there and made snow cones.
Snow Cones on Venus. I'll think I'll write a short story with that title.
