In 1977, during the BBC documentary "Pathway to the Gods", Uschuya produced an Ica stone with a dentist's drill and claimed to have produced a fake patina by baking the stone in cow dung. That same year, another BBC documentary was released with a skeptical analysis of Cabrera's stones, and the new-found attention to the phenomenon prompted Peruvian authorities to arrest Uschuya, as Peruvian law prohibits the sale of archaeological discoveries. Uschuya recanted his claim that he had found them and instead admitted they were hoaxes, saying "Making these stones is easier than farming the land." He engraved the stones using images in books and magazines as examples and knives, chisels and a dental drill. He also said that he had not made all the stones. He was not punished, and continued to sell similar stones to tourists as trinkets. The stones continued to be made and carved by other artists as forgeries of the original forgeries.
