These falls where formed about 12,000 years ago when the glaciers departed leaving the great lakes. The waters of Lake Erie ran downhill over the Niagara Escarpment to Lake Ontario carving out a fast-flowing river and picturesque gorge. The river flows over two falls on its path from lake to lake creating both the Horseshoe (Canadian) and American Falls. Awe-inspiring to behold, both falls have attracted adventurers and tourists for centuries. This calendar celebrates the beauty of the Niagara River Gorge and two falls. Produced via environmentally friendly processes, using chlorine free FSC-certified paper and vegetable-based inks, this beautifully photographed 16-month 12 x 12 wall calendar includes an additional page featuring smaller grids of the months September, October, November and December. This wall calendar is produced in English format.
