Niagara Falls
"There reigns in this place a profound and terrifying obscurity, now and again relieved by a flicker of light. Then you see the whole river, seemingly descending on your head. It is difficult to describe the impression produced by this ray of light, when having let you a moment glimpse the vast chaos which surrounds you, it abandons you again amidst the darkness and fracas of the cataract."
Tocqueville, letter to his mother (Pierson 310)
