All rights reserved.In the high ravines of the mid Calchaqui valley, Salta province, we have found a series of Inca sites and roads that led us to postulate the importance of transversal communications between mesothermal valleys and Puna environment in this area of the Tawantinsuyu. Based on the archaeological record and historical information from the 16th, 17th and 18th centuries, we discuss the possibilities of communication between different geographic and environmental units.
