I really believe there is a proper name for this seasonal happening; I just can't nail it down. They have been created by lake ice being forced to shore, high splashing waves freezing over top for months on end.
These images shot at a location known in this Province as Wasaga Beach. It is recognize as being the world's longest freshwater beach at 6 miles.
Summers find this beach packed solid. Not so much in the winter.
Difficult to grasp from the original, but these ice dunes here are actually 8 FEET high. I attempted to use the people to show scale but not so well.
3 additional Versions give different scales, all of them nearly 12 feet tall and at the bottom an unfrozen lake and maybe 2 or 3 feet of water.
Taking these shots I was at the lowest point which would have been the beach.
