This monotonous drive will terminate in Lewiston, New York, a village 30 minutes north of Buffalo, where there are coffee shops, art galleries, and historic hotels, all set along the banks of the Lower Niagara River. Twelve-thousand years ago, Niagara Falls plummeted over the Niagara Escarpment here, but centuries of erosion have moved the 8th Wonder of the World 7 miles upriver. The falls continued retreating 3 to 5 feet closer to Lake Erie each year, until water management over the past century reduced that number to about 1 foot. The hydroelectric plants that divert the water from above the falls and deposit it in the lower river generate one-quarter of the electricity used in New York and Ontario, Canada. Even with some of its power harnessed, Niagara Falls still pulverizes enough limestone, shale, and sandstone to give an aquamarine cast to the Lower Niagara’s waters.
