In 1969, Don Fornasari filmed an excursion in the area of Lago Nero (Black Lake), Monte Bue Hut (Rifugio Monte Bue), and the Umberto Sacchi Bivouac, on the Piacenza Apennines. The film presents two superimposed scenes: on one side, a group of young people camping on the lake's shores, and on the other, shots from above of the huts and surrounding slopes. The images show young hikers crossing meadows and rocky terrain under low clouds and mist, alternating with panoramic views of the mountains. From the Monte Bue Hut, people are seen ascending the slope aboard the historic 1960s chairlift (cestovia), built between 1964 and 1966 by the builders Marchisio and Doppelmayr, which connected Rocca d'Aveto to the summit of Monte Bue with a stop at Prato Cipolla and which would be dismantled in 1992. The final frames show the Umberto Sacchi Bivouac, a building constructed in 1966 and renovated in 1999, maintained over the years by CAI Piacenza as a base for hikers and mountaineers.
