Guyana were considered: Kaieteur National Park, Shell Beach and Historic Georgetown. By 1997, work on Kaieteur National Park was started, and in 1998 work on Historic Georgetown was begun. To date, however, Guyana has not made a successful nomination. Guyana submitted the Kaieteur National Park, including the Kaieteur Falls, to UNESCO as its first World Heritage Site nomination. The proposed area and surrounds have some of Guyana's most diversified life zones with one of the highest levels of endemic species found in South America. The Kaieteur Falls are the most spectacular feature of the park, falling a distance of 226 metres.
American Falls can view the falls from the bank of the river, as well as on Goat Island and Luna Island, which are accessible by a pedestrian bridge that crosses the rapids of the Niagara River upstream from the falls. The falls are viewable head-on from the Canadian side in Niagara Falls, Ontario. The ledge of the American Falls is shaped in a modified "W" form, caused by numerous rock falls over the past 150 years which have resulted in the huge mound of rock at its base. The most notable recent rockfall occurred in 1954 with the collapse of Prospect Point
