Hikers in the remote Peruvian Utcubamba province have discovered a few well-preserved buildings near a towering waterfall. The buildings are believed to have been left by the mysterious Chachapoya people, who were conquered and incorporated into the Inca Empire not long before the arrival of the Spanish. The ruins are win good shape, and according to archaeologists appear to be untouched by looters. The structures are built high into a cliff wall and it is theorized that they may have served as lookout towers. As yet there is no word on when and if the archaeological site will become open for tourism.
