December 27, 2003, a crisp and sunny day, perfect for a hike. Greg and I went to Big Ridge State Park in east Tennessee . Soon we came upon a cut off log with a giant icicle extending out of the lower end. It must have been below freezing for many days to get an icicle of this width and length. But, it must have been warm enough in the log and the soil to keep the water flowing so the icicle would keep getting a supply of water.
