That’s our ship, floating in the mouth of the gigantic volcano. Santorini (part of the rim of the caldera) looks like it’s made of sedimentary rock, but it’s actually layers of volcanic ash. There is ash accumulating even today.
This is the biggest volcano in at least 10,000 years of history on the earth. The main volcano is still active, as is another volcano under water. Volcanic dust is accumulating every day on the island. People are whisking it away and cleaning it off their cars. You can see it in fields, about eight inches of dust that will eventually harden after a few million years.
The snowy peaks on the island are actually whitewashed houses.
I bought three mathematics-themed T-shirts on Santorini. There were tons of brilliant designs, and I could have bought dozens.
According to Betty’s phone’s pedometer, we climbed fourteen storeys on Santorini.
Another crazy T-shirt design.
All the grape vines are kept low to the soil, out of the wind. They are woven into little basket shapes to hold the grapes. Once that was explained to us, it was obvious that the whole island is planted in grape vines.
The residential/hotel part of Oia, Santorini.
We took a cable car down to the ship (there was no other option. Well, there were donkeys.). It was quite terrifying for some, not so much for others. Here’s a stock photo of the cable car:
The cable car mechanism. I have a movie of this.
