In Yuty’s Aguaray stream there are deposits of magnetite, the itakaru or “stone that eats”: local belief holds that it brings good luck if you “feed” it bits of steel. The town’s main festival, created in 1982 as part of the September 8 patron saint celebrations, takes its name from it. It’s a festival of music and get-togethers in one of the south’s towns of colonial origin, home to the 1909 Fierro Punta railway bridge over the Pirapó River.
