El Pedrigolet is the name given to this scree slope with small rocks at the foot of the Cau del Duc. The Cau del Duc is a cave created by water filtering water through the carbonate rock of the mountain. This cave was used by prehistoric people since ancient time, in the Lower Palaeolithic (some 300,000 years ago), as a place to shelter. Excavations have found large amounts of utensils, stone tools and bones of animals eaten by the people. Many of these remains are in Can Quintana, the Mediterranean Cultural Centre.
At the Tartera del Pedrigolet, until a few years ago, there was a local tradition that on Saint Catherine’s day, many people would go down it by jumping. Unfortunately, this tradition has made the rocks ever lower and scarcer.
