Cerro Tololo
The following day the ship called at Coquimbo, where I took a tour bus to go up to the Cerro Tololo observatory.
On the way to the Elqui Valley we passed this modern water tower, decorated in the style of the ancient inhabitants of the area.
The road, whose only function seems to be access to Cerro Tololo and to the nearby Gemini South telescopes, is quite steep.
The towers for the four meter and one and a half meter telescopes, along with other smaller ones, are at the highest point in the neighborhood.
Returning down the mountain (good brakes!) we saw the site of the Gemini South telescope. This 8 meter telescope, closed to casual visitors, is the twin to Gemini North in Hawaii.
