It would seem I was incorrect and we are temporarily living in the UP. Those are snow coated icicles up to 3-4 feet long and maybe 1.5 foot deep by something like 5-7 feet out overhang of snow. It’s a corner I couldn’t reach yesterday with the snow rake. Although it also didn’t look like this. High winds and frigid temps create avalanche hazards. On your roof.
