You can take the train from Aguas Calientes back to Cusco if you like but you would be missing a lot. My traveling companions and I drove back. We made an important detour from the Valley of the Incas up into the mountains to Moray. It is 11,106 feet above sea level and is an agricultural center in the high plains. Fields were being prepared for the rains to come in May and June. Many varieties of potatoes are grown here, as is barley and corn.
On the way to Moray, we came upon this.
A single flower in dry grassland. It elicited considerable debate and I had to turn to a higher authority, Panayoti Kelaidis, for help. With much electronic to and fro, he came up with this – Pyrolirion. Pyrolirion tubiflorum or Rhodophiala bagnoldii or Rhodophiala auracana. Whatever the or, it is a lovely bulb.
Moray has a very interesting and beautiful set of ruins. Lifting from Wikipedia – “The site contains unusual Inca ruins, mostly consisting of several terraced circular depressions, the largest of which is approximately 30 m (98 ft) deep. As with many other Inca sites, it also has an irrigation system.
The purpose of these depressions is uncertain, but their depth, design, and orientation with respect to wind and sun creates a temperature difference of as much as 15 °C (27 °F) between the top and the bottom. It is possible that this large temperature difference was used by the Inca to study the effects of different climatic conditions on crops. Speculation about the site has led to discussion about Moray as an Inca agricultural experimentation site”
And with that, we staggered back to Cusco and on to the next adventure.
