This photo embodies the experience of those of us who grew up in Niagara Falls during the 1950s and 60s. The girl is gazing toward the brink of the Horseshoe Falls from a treacherous perch on one of the Three Sisters Islands. One misstep would take her “to Eternity,” as the writers of the 19th century would say. Today, the waters are diminished by diversion for power, and barriers try to keep people on the trails, and not clambering over the rocks. The essence of the Niagara experience is awe of Nature’s power tempered with the reality of our own flimsy mortality. (Photo by the late Buffalo photographer Joseph P. Driscoll)
