5/31/2008--Niagara Falls, New York and Canada; 167' high; Elevation 581' on US side, 617' on Canadian side; The Horseshoe Falls (Canadian) drop about 187 ft,^[4] while the height of the American Falls varies between 69 and 98 ft because of the presence of giant boulders at its base. The larger Horseshoe Falls are about 2,590 ft wide, while the American Falls are 1,050 ft wide.

I couldn't find an 'N' waterfall in Utah so I am using Niagara Falls which we visited in May of 2008. It was a sight to see. We enjoyed watching the falls from both sides of the border.
