It doesn’t matter if you believe in evolution or not; Volcanic magma erupted from the Earth’s mantle to create the Galapagos island archipelago thousands of years before we were born.
Visiting Santa Cruz island yields two very distinct and different climates and ecosystems based on which side of the island you’re on. The northern (leeward) side of the island is a barren, drought-stricken landscape consisting of cacti, volcanic rocks, and only the heartiest animal species. The southern (windward) side of the island is a lush, tropical ecosystem full of forests, farms and the majority of island’s animals.
When heading into town from the airport, there’s an exciting Geologic landmark half-way across the mountainous island. A few small signs mark the attraction, and easy to miss unless you’re looking for it.
Los Gemelos, commonly called “The Twins” is a pair of pit craters located in the center of Santa Cruz island. The collapse of a magma chamber formed both of the craters sometime long ago. The holes are giant and estimated to be a few hundred feet deep with sheer cliffs surrounding the dense vegetation below.
There’s no access to get in the craters; repelling is your only option. There are walking tours around the rim of the craters which give you a good view of this impressive formation; however, the view from a drone puts things into perspective.
