There is a time and a season for everything under heaven and this is the time for ice. Conditions have to be just right for icicles to form. The snow has piled up unmelted on our roof for a couple of weeks and now the temperatures are high enough during the day to start the snow melting and then freezing when it trickles down from the gutters or the roof. I am interested in the branching near the end of the ice. These ice formations remind me of helictites in the caves I have explored. I am guessing that the same forces that form these branches in icicles also contribute to the helictites.
