Engineering Interpretation
Niagara's thunderous beauty conceals an industrial marvel, where water is relentlessly corralled through monumental tunnels and titanic turbines to power two nations, proving that even the most breathtaking natural force can be put to work with enough concrete, steel, and sheer human audacity.

Geology Interpretation
While the falls today may appear to move with the slow-motion dignity of a glacier (just 6 cm a year), they're actually a geologic speed demon that has raced seven miles upstream over the last 12,000 years by relentlessly chewing through 420-million-year-old rock.

History Interpretation
From a priest's awestruck sighting to a treaty's measured diplomacy, Niagara's history is a roaring balance of daredevil folly, tactical power grabs, engineering marvels, and preserved majesty, proving that even nature's most spectacular curtain call has been a stage for human audacity, conflict, and eventual, if sometimes clumsy, reverence.

Hydrology Interpretation
Niagara Falls, that hydrologic show-off, operates under a strict international treaty requiring it to pour a minimum of 100,000 cubic feet per second during the day, yet slyly diverts up to 75% of its flow for power at night, making its nighttime performance a mere shadow of its spectacular, 225,000 cubic-foot-per-second daytime peak.

So despite the dramatic, chaotic data dump, Niagara Falls essentially amounts to a massive, three-part liquid staircase roughly as wide as the Empire State Building is tall, which is very politely taking its time—one foot per century—to walk backwards away from Canada.
