Last week the Niagara Parks Blog posted some information about Journey Behind the Falls turning 125:
For 125 years over 50 million people have experienced the awe-inspiring spectacle that is Journey Behind the Falls. It has captivated its visitors throughout time with its rich history and awesome power. Over one-fifth of the world’s fresh water crashes 13 storeys to the basin below. During summer daylight hours, over 2,800 cubic meters of water thunders over the brink every second, traveling 65 kilometers per hour.
