Šomoška stone waterfall (opens in new tab)

On the borderlands between modern-day Slovakia and Hungary stands one of the strangest waterfalls in Europe. The formation at Šomoška Stone Waterfall appears frozen in motion, as though a cascade of dark basalt had suddenly solidified while tumbling down a hillside. Unlike ordinary waterfalls shaped by flowing water, this “stone waterfall” was created by volcanic fire millions of years ago.
