The Pierres du Niton (French for Neptune's Stones) are two glacial erratics in Lake Geneva, Switzerland, in Geneva harbor. On the left bank of the lake near Quai Gustave-Ador, they are remnants from the last ice age, left by the Rhone glacier. Because of their role in Swiss cartography, the rocks have been declared a "Geotope", a national site of geological heritage.[1]
