Reichenbach Falls
The Reichenbach Falls was a waterfall located near the Swiss town of Meiringen. The falls were most famous for the fictional encounter between Sherlock Holmes and James Moriarty, during which the two men struggled and fell over the falls. At first both men were presumed to be dead, but in fact Sherlock Holmes survived.

In 2365, Data mentioned the encounter at Reichenbach Falls after deducing that the holodeck had created Professor Moriarty as an opponent for him. ()
