Overnight we sailed over 80 nautical miles, to get to the most mysterious and fascinating part of the Galapagos Archipelago, the geologically young western islands. Still actively being fed by the Galapagos mantle plume, signs of their young age are everywhere as we hike over lava flows and cruise along volcanic structures of different origins. Situated at the edge of the Galapagos Platform, this area is also where the cold, productive waters of the Equatorial Undercurrent upwell, bringing an abundance of marine life to the area, much of which was seen during our sailing, Zodiac riding and snorkeling activities.
