Geology & Volcanology
Santiago Lake occupies an elongated crater with an N-S direction. Its walls are rocky and steep, covered by pumice stones. Other pyroclastic materials also cover these walls.

As for its curious name, it may be explained by the Azorean chronicler of the 16th century, Gaspar Frutuoso. He referred to it in his volume IV of Saudades da Terra: What to do after visiting Lagoa de Santiago.
“…its depth and high concavity of this Santiago lake are frightening to those who see it. That’s why it seems they named it Santiago. When we see something dangerous, we immediately say — Santiago — invoking the name of the patron saint of Spain. May God protect us from it.”
Fauna & Flora
Gracefully protecting this lake is the vast vegetation of Cryptomeria japonica, incense (Pittosporum undulatum), Hedychium gardneranum, among many other elements. These elements of its natural vegetation include holly (Illex perado ssp. azorica), laurel (Laurus azorica), and mountain grape (Vaccinium cylindraceum).
