Back to the northern shores. The water is just beautiful. Those rocks are at least 30 feet high.

Another of those volcano crater lakes. Actually two of them. The Green Lake (smaller one) and the Blue Lake (bigger one).

These birds are fairly common in the mountains here in Sao Miguel island. I believe they are European Robins. This one was fairly fearless and sat next to us in the bench and did not even flinch as I took a few pictures.

Found out that bulk of Sao Miguel’s power comes from geothermal energy. Those pipes – I assume – are carrying hot water. One thing I could not figure out is the weird shape of the pipe. At one time, I came close to the pipes and saw a dirt road run under one of those “gates”. But that cannot be the purpose. If you carefully look, there are those “gate” structures horizontally too.

Do you think this could be to allow for expansion due to temperature fluctuations?
