An Icebridge is when ice forms below Niagara Falls from the Canadian to the American side of the river.
It occurs when we have very cold weather (which creates ice in the upper river) followed by a warm spell. This warm weather breaks up the ice in the upper river and Lake Erie and it starts to low downriver over the falls and plugs up just below the falls. That’s the conditions we had this past weekend resulting in the formation of a very thin icebridge below the Rainbow Bridge. Years ago people would walk on these icebridges. They were much larger at that time.
It is illegal (and foolish) to venture out onto these bridges. The icebridges make for great photography. This photograph was taken at 10 a.m. this past Saturday.
However, the warm weather we had today and yesterday melted the icebridge that I saw this past weekend.
