While hiking the Inca Trail lat week in Machu Picchu ,Peru I came upon a circular bronze marker cemented in the ground near the Inca bridge. It is labeled "Santuario Historico De Machu Picchu, 2006, (a triangle), Punto Geodesico, Orden C, 138". I have a photo, but do not know how to post it on this page. Is this marker considered a benchmark? Thank you. Nuffie
