The Mighty Niagara River Plummets Some 180 Feet ...

The mighty Niagara River plummets some 180 feet at the American and Horseshoe Falls.

Before the falls, there are violent, turbulent rapids. Farther upstream, however, where the river’s current flows more gently, boats are able to navigate.

Just before the Welland River empties into the Niagara, a pedestrian walkway spans the river. Posted on this bridge’s pylons is a warning sign for all boaters: "Do you have an anchor?" followed by, "Do you know how to use it?"
