Ness Lake froze into perfect glassy ice this particular year, without wind or snow. Created by shining a high intensity LED flashlight to illuminate some of the foreground cracks in the ice. The fractured ice reflects light along the cracks, much the same way light travels along optic fibre. Any light which escapes the primary fracture travels away sideways through the ice without being visible to the observer above, unless picked up by another crack and reflected upwards. Northern BC, Canada.
