Treasure of the Niagara

Niagara Falls is a wonder to behold, with its thundering sheet of water and a roar almost deafening in its intensity. They are one of the most famous attractions in the world, visited by millions of people every year who marvel at its natural majesty and the sheer power it represents.
Everyone the world over seems to realise that Niagara Falls is a treasure. But what few realize is that a treasure also lays under the churning, white-capped waters, a treasure that has only revealed itself once in history.
