BATOPILAS: Located at the bottom of Copper Canyon, Batopilas, now a sleepy little village, was once one of the richest silver mining areas in the world. A visit to Batopilas is a step back in time. Cowboys ride their horses down its dirt streets while Indians pack their burros with supplies for their remote villages. On the outskirts of the town are the ruins of a Gothic mansion built in 1880 of adobe by Alexander Shepherd, an American entrepreneur and the last territorial governor of Washington D.C., and a 400-year-old Jesuit mission known as the “Lost Cathedral” of Satevo.
