Prospect Point Viewing Area -- Niagara in the Winter:
Ice from Lake Erie flows over the falls and jams up in the gorge below. An ice bridge is an accumulation of ice, which has frozen solid from shore to shore, and under which the river still flows.
In the past, the American Falls and Bridal Veil Falls were frequently reduced to a trickle when ice jammed up in the American Rapids. A few times both falls completely froze over! Since 1964, the installation of the ice boom, a barrier laid across Lake Erie, slows the amount of ice flowing down towards the falls. |
