Inward Tilting Icicles :: Part V :: French Curl

The following photo came through as the last photo in a French PowerPoint presentation of prize photography: Sur_le_vif.pps or Sur_le_vif.ppt. (If anybody finds it on a web site let me know) Not only is it beautiful, but it challenges our wisdom of last winter. Is this merely the result of gradual slipping? Is it differential freeze and melt? Postscript: Peter the spelunker notes: Stalactites can do this also in caves. Since they grow from the inside out, a blockage of the water channel or wind directions change can lead to those formations.
