In 1969, Don Fornasari documented a short excursion to Lago Nero (Black Lake), in the Piacenza Apennines, in the territory of Ferriere. The camera films a person walking towards the lake from above, alternating views of the lake (black only in name, actually green due to the reflection of the dense vegetation surrounding it) and the peaks overlooking it, including Monte Nero and Monte Bue. The images show panoramas of the mountains and rocky walls, along with glimpses of the still water set in the glacial basin at 1540 meters of altitude.
