Before long March will arrive, and the opportunity to see impressively huge ice pans floating downriver, tumbling off the elevated portion of the river just beside the falls into the river below, their weight causing them to sink in an immense splash of freezing river water, surfacing soon afterward to continue their journey downstream will beckon. It's quite the sight, fascinating to watch as this hugely thick ice sheets slide past, crash below and float serenely on.

When we first saw this yearly event, we were amazed. The power and majesty of the natural elements that surround us never fails to impress us. In the event, this key-cutting exercise is a preemptive effort to forestall flooding, a natural enough occurrence that can have grave consequences to public safety and the destruction of the hundreds of buildings existing along the river shoreline.

weight alone. If that doesn’t work, the hydraulic arm can finish the
job. Photograph by: Chris Mikula, The Ottawa Citizen
