What is the highest waterfall in the world?
Niagara is still impressive but it doesn’t make it in the height department. If you google Niagara cam you can get live pics, real time. You can even pan and zoom the camera right from you computer. It is pretty neat. The highest one I have seen in person is Multnomah Falls in Oregon. I think it is 620 feet but there is an upper and a lower section to it and I would guess the 620 is the sum of both. Here is a picture. I bet they have a cam for that too. http://www.motorcycle-usa.
Niagara Falls is not even in the top 10 tallest falls. Angel Falls (Venezuela) is the world’s tallest at 979 metres. Niagara Falls is only 52 meters tall. The tallest falls in North America is James Bruce Falls (BC Canada) at 840 m. The tallest falls in the US is Colonial Creek Falls (Washington State) at 788 m.
