Niagra falls, one of the wonders of the world, right on the border with Canada and some twenty miles north of Buffalo(布法罗，美国纽约州西部 一城市), USA, is a must to see!! At 56 metres (180 ft), the American Falls is slightly higher than its Canadian counterpart. Its crestline (瀑布最高处的宽 度) is 320 metres (1075 ft) . The American Falls look spectacular at night, when it is lit with various combinations of coloured lights. Over the last century the American Falls has undergone a dramatic face lift due to natural forces of erosion (腐蚀, 侵蚀). The natural bedrock ([矿]岩床) is composed of (包括，包含) soft shale (页岩) and limestone ( 石灰石). Over the years the continual flow of the water causes large sections of the bedrock to fall and remain at the base of the cataracts (大瀑布). It is estimated that 75,000 gallons of water flow over the American Falls each second, amounting to only 10% of Niagara's total waterflow. No one has ever dared to conquer the American Falls in a barrel (桶). All daredevil (鲁莽大胆的) activities have always concentrated on the Canadian Horseshoe Falls (加拿大马蹄瀑布) because it has a larger waterflow and fewer rocks at its basins (底部).
