Winter weather 2014
- Jareen, CNN iReport producer
"Those ice formations are called ice spikes. They form when water freezes and expands. The water first turns to ice around the edges of the enclosure holding the water.
The freezing spreads inward until at some point there is a small hole or opening that remains on the surface. The expanding ice starts to force water upward thru the opening forming a tube of ice straw.
The water slowly spills over the top and freezes on the outside rim causing the tube to lengthen. The tube will stop growing when either all the water from below freezes or when the tube freezes shut forming a solid spike of ice.
I suspect that a light wind may have caused the spikes to grow at an angle so that they appears much like a pair of radio antenna would look."
This was an odd winter wonder and I was happy I found before it melted away later in the day.
