Yes! Every where you look, you'll find an incredible geological feature in the Galapagos! Over millions of years, land-forming and land-degrading processes have shaped these enchanted islands to provide a unique set of ecological conditions to which life in the archipelago has had to adapt or die. That was one of the main attractions today. Part of our afternoon was focused on the visit to an area located in the highlands of Santa Cruz. Everyone thought, when looking at a huge hole on the ground, that it was a caldera from a volcano. The truth is that these particular "calderas" were formed by the subsidence of the upper parts of the volcano when the underlying structure was weakened and the magma retracted. We were not visiting a recent volcano, therefore it was not a caldera what we were looking at. What we can see in the picture above is in reality a "sink hole". It's round shape leads us to believe that a considerably amount of gas was trapped in its interior, and when this was released through vents collapses were unavoidable. We were really impressed to see such a majestic display of power and perfection.
The Galapagos Islands are amongst the most active volcanic regions on earth. The process of island formation has continued on and off up to the present day, and will probably continue for millions of years.
