The Mining History Trail leading into the Val Minor provided information about mining in the valley. Explanations were given about rock deposits in the area and the formation of mineshafts. Eight information boards led from the Lagalb valley station to the Bernina Pass height in the Camino gallery, the only one still accessible, afterwards to the pyrite - arsenopyrite occurrence and also via the Fuorcla Minor. The two tunnel districts and the hut Fuorn d'Plattas from 1458 also belonged to the stops.
