Today I got a nice postcard from Canada! The postcard shows a beautiful view of the Niagara Falls, arguably one of the most iconic waterfalls in the world. Niagara Falls is located on the border between Canada and the United States of America and it is considered to be one of the 10 Natural Wonders of the World. Its total height is 51 metres and has a total of three drops. Its average flow rate is 2,400 cubic metres per second. Thanks Graycee!
