Enter the jaguar: psychedelics in ancient Peru

Enter the jaguar: psychedelics in ancient Peru: The monumental ruins of Chavín de Huantar, ten thousand feet up in the Cordillera Blanca of the Peruvian Andes, are, officially, a mystery. The vast, ruined granite and sandstone structures – cyclopean walls, huge sunken plazas and step pyramids – date from around 1000 BC but, although they were refashioned and augmented for close to a thousand years, the evidence for the material culture associated with them is fragmentary at best.
