This important quarrying basin, located to the NE of Torano in the Torano valley (also named Valle del Pianello or Valle dei Marmi in old literature), includes about 50 quarries (22 of which are still active).

The Torano valley is drained by Fosso del Lupo, a stream originated from the tributaries of several streamlets draining the area between Monte Uccelliera and Monte Borla (Canal Bianco, Canale Conca, Canale Ravalunga, and Ravaccione). It receives two right-bank tributaries: Canale di Lorano, which in turn receives the left-bank affluent Fossa degli Angeli, and Rio di Monte Pesaro. The main stream (Canale di Torano) originates just upstream of the village of Torano by the confluence of Fosso del Lupo (whose last segment is also known as Canale di Sponda) with Canale di Bucceta.
