Less than 14,000 km from Ruakuri and Waitomo caves, there is another natural phenomenon that is much more famous than - and strikingly different from - glowworms, but similarly striking, at the same time.
Niagara Falls is a wonder everybody has heard of, while millions have seen colourful postcards devoted to it, or even visited the famous site itself. They were taken into deep tunnels running behind the Falls and almost brought amidst the whirlpool itself by the “Maid of the Mist” (and the mist is so thick as if the whole mass of this perfectly chilly water were boiling day and night). A platform was built to suit those preferring to socialize and take pictures – and nobody is allowed there without a wet-resisting cloak because the platform is more soaked with water than a low ship deck. The Falls have for decades been viewed from every possible angle; yet, I had a fleeting impression that they had remained as new and mysterious as ever - that “Rapidly Motionless Wall” breaking apart every single second and getting instantaneously rebuilt out of water.
