From My Web Times:
…there is no single waterfall actually named “Niagara Falls.”
Originating at the east end of Lake Erie, the Niagara River flows about 21 miles north from Buffalo, N.Y., to Niagara Falls, N.Y.
Here, the river forms three waterfalls, divided by a landmass known as Goat Island.
On the island’s east side, the 184-foot tall American Falls combine with the smaller Bridal Veil Falls to stretch 1,060 feet from the mainland to Goat Island.
On the west side, the 2,600-foot long Horseshoe Falls, or Canadian Falls — the 175-foot-tall, roughly U-shaped cascade commonly photographed as “Niagara Falls” — plummets into the 185-foot-deep Niagara Basin.
Collectively, these three are what most refer to as Niagara Falls.
