Stalactites (pointing down) and stalagmites (pointing up) don’t just form from cave minerals; they can develop in ice, anywhere dripping water can freeze. In this weird scene, they joined after hours of dripping from the log above, forming ice columns in some very cold air (below 15 degrees F). Some of that dripping was related to waves and spray before the lake surface froze.
