"The Niagara Glen is today a favourite site for thousands of visitors each year. It is a beautiful picnic area located on the top of the Wintergreen Flats and nature trails to the river below are well marked and plentiful. This is the site of the Falls of Niagara 6,000 - 7,000 years ago. The water falls at this point was 37 meters (120 feet) to the water pool below."
The Maid of the Mist tourist log would have had to embark passengers about 2 miles further downstream from the present Falls site. I'm not sure how much wampum a ticket was back then. The cheesy tourist museums didn't have too many exhibits.
