Machu Picchu: A Civil Engineering Marvel takes readers inside the Lost City of the Incas for a groundbreaking perspective never before seen by tourists or archeologists. Built high in the Andes on a seemingly impossible site, Machu Picchu stands as a testament to Early Native Americans and their ability to plan and build. How was it possible to create a mountain-top city complete with running water, drainage systems, food production, and stone structures so advanced they have endured for over 500 years? Authors Kenneth R. Wright and Alfredo Valencia Zegarra explain these and other mysteries, based on their original engineering and scientific research. A fascinating book, ""Machu Picchu: A Civil Engineering Marvel"" is a must-have for civil engineers, archeologists, armchair travelers, and tourists alike. An illustrated walking guide and detailed map allow readers to become familiar with each building and pathway, and numerous photographs take readers on a breathtaking pictorial adventure.
