From here, the observer can closely examine the detachment niches left behind by the palaeo-landslide (50 million m3) which, about 10,000 years ago, affected the southern slopes of the Mounts di Rivo and Cucco. The material poured into the Bût valley, blocking it and creating a lake. The two niches are different. That of Monte Cucco is stabilized and now mostly covered by vegetation, while that on Monte di Rivo has been affected by intense erosion phenomena (still in progress) and runoff that have created unusual morphologies in the form of pinnacles and rock towers ( the Lander Cjampanii or “belltowers”).
