This boulder is called Grossi Flue. It weighs a whopping 3,500 tons and has a volume of 1,200 cubic meters. The boulder was brought here by the Rhone Glacier – this is evident from the hornblende gneiss. The enormous boulder was purchased by the Swiss Society of Natural Sciences in 1869 and placed under protection. Otherwise, it would likely have fallen victim to railway construction.
