When the day became light enough to see, the outline of Floreana could be seen south of our anchorage. Very different profiles from the previous two islands visited on this expedition in Galapagos. We are still in the southeastern corner of the archipelago, still in the realm of island endemics within the Galapagos endemics. Floreana has its own lava lizard, prickly pear cactus and mockingbird species, and even its own marine iguana subspecies. Very isolated indeed. Over the day, we covered the northern shore of the island, exploring on land and in or on the ocean in protected waters, in the lee of the island, away from the dominant southeast trade winds and Humboldt Current that hits the southeastern cast pretty hard year round.
National Geographic Endeavour II
Española is the oldest of the Galapagos Islands. It sits on the southeastern end of the archipelago. The Galapagos are volcanic islands that formed over a geological “hot spot.” As the tectonic Nazca Plate slides to the southeast over the volcano-producing area, new islands emerge. This means that the islands towards the northwest are the youngest and the ones on the opposite end are the oldest.
