Today we explored Sullivan Bay, in Santiago Island, and Bartolome Island. In the morning we explored a relatively new lava flow, where we learned about the geology of the Galapagos during the early stages of these volcanic islands. In the afternoon we explored Bartolome Island, where we enjoyed unique moments spotting animals such as Galapagos penguins, sea lions, blue-footed boobies, and many sea creatures during our snorkeling activities. We finished the day celebrating the wonderful expedition we just had on board National Geographic Gemini.
