World's most extreme toilet

Located in Siberia, Russia, the world’s “most extreme” toilet rests on the edge of a cliff 8,500 feet above sea level. This washroom only serves the five people working at the weather station on the Altai Mountains. For their other necessities, such as food, water and firewood, a helicopter visits them once a year to stock up. A postman visits them once a month to collect the weather data as well.
