FIGURE 1: a: Fischer's Tower in Hell's Gate National Park, Naivasha, a 25-m high rocky tower (so-named following Fischer's departure through the area from the lake to the Mount Suswa side of the Rift Valley in Jun 1883). It was formed by semi-molten rock forced up through a fissure in the earth's surface, cooling and solidifying as it emerged. According to Masai oral tradition, the tower is a Masai girl who was turned into stone after disobeying the family before her wedding (photo courtesy D.A.
