We had a tour of Machu Pichu. Our guide took us all over the place and he knew a lot about the Incas. We walked up a lot of stairs to the main entrance for the Inca Trail. The ruins were neat. No one really knows what Intiwatana is.
Some people think it was used as a calendar, a sundial or an observatory.
The archaeologists have also discovered Intiwatanas in Cusco and Pisac. The view down to the Urubamba River from here was really nice. There were a few other stairs like this. There were a lot of stairs to climb up the mountainside. Our guide led us to a meteorite.
