besides, Niagra has the pure awesome power that georgia's falls will never have. beauty is in power.
Unfortunately there was one moment when Toccoa Falls (which is higher than Niagara, by the way

) became extremely powerful and deadly. Back in 1977, after 2 days of torrential rain, the dam behind the falls broke. A 129-million gallon wedge of water 30 feet high thundered over the falls, travelling at 120 miles per hour. Huge boulders and tree trunks tumbled before it. Look at the picture above and just imagine if you'd been standing there at that moment. The wave smashed through homes and a trailer park, flinging rocks and debris in its path, and it devastated the campus of nearby Toccoa Falls Bible College. 39 people lost their lives, including three students who were housed in the basement of one of the college buildings.
According to the Christian History Institute:
"Survivors sang and prayed while sitting naked and muddy above the receding waters. Some thanked God in the moment of terror, remembering his command to give thanks in everything...Pat Sproull rode a roof to survival. While in the hospital, she learned that her three daughters had died. Asked how she could be so strong (she was comforting others through tears, despite her personal tragedy), she replied, 'We gave our girls to God long ago, even before they were born. He's just taken them now'...After the disaster, a reporter asked one of the professors how he would vindicate God to the students after the disaster. 'The question has never even come up,' replied the theologian. Most of the students believed that God was in charge of their lives--not themselves."
Quite a story. But back to the topic of whose waterfalls pwn (and I take note that CS's waterfall image is suddenly nowhere to be found

), I think it will depend on what you like in a waterfall. If you like waterfalls that are beautiful, approachable (in that you can even swim at the base if you want) and secluded, you just can't beat the personal favorite of Mirawyn and I: Helton Creek Falls, near Blairsville GA.
And if its power you want, you can actually WALK behind Dry Falls in Highland NC (VERY close to the GA border, so I'll just claim it for GA

) and stand there as the water crashes down in front of you. Believe you me, that's plenty enough power when you're that close!

So in conclusion - sorry, but the Southern Appalachian's waterfalls pwn all else.
