Roques de García
Roques de Garcia are a group of rock formations formed 200,000 years ago as a result of the collapse of the Las Cañadas caldera volcano.
The collapse was probably multi-staged and was not typical vertical collapse which is how calderas usually form. The caldera of the Las Cañadas is a result of a lateral flank collapse.
