The name refers to the fact that humans can easily walk behind falls and not get wet. If the wind is calm, we stay dry. ... But if it is windy, we do get a spritz. :) Yes, there is a lot of water. This is the Cullasaja River falling as it runs down the mountainside. It is a short river, doesn't even make it out of Macon County. It originates just west of the Eastern Continental Divide so the water runs through several different rivers and eventually ends up in the Gulf of Mexico. The waters on the other side of the mountain run along until they join the Atlantic Ocean.
