In that 2nd photo from last Sunday, those are water/wave drips freezing on that railing. They are freezing on an angle because the wind is blowing 30 mph from left to right on that photo. Cool stuff. The Great lakes are fascinating.
Jerry, you mention power. There are railings like the ones in the picture out on the main breakwall that are bent from water and ice rushing over. That's 6" heavy wall pipe....bent 6-12". The water level is about 7-8' below the breakwall so that's probably 12+ foot waves busting over the wall.
