Martigny (German Martinach, Latin Octodurum, sometimes also Octodure in French) is the capital of the French-speaking district of Martigny in the canton of Valais in Switzerland. It lies at an elevation of 471 meters (1,545 ft), and its population is approximately 15000 inhabitants (Martignerains or "Octoduriens"). It is a junction of roads joining Italy, France and Switzerland. One road links it over the Great St. Bernard Pass to Aosta (Italy), and the other over the col de la Forclaz to Chamonix (France). In winter, Martigny is appreciated for its numerous nearby Alp ski resorts such as Verbier.
A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.
