They look like something you might find in a botanical gardens display. Six-sided columns, jutting out of the earth below, arranged in seemingly perfect order, alongside a beautiful lake fed by a tranquil waterfall; their formation looks almost too intentional. But the Basaltic Prisms of Santa María Regla, a collection of striking rock columns jutting out the side of a valley in Mexico, are no man made creation.
The prisms, made of igneous rock formed in the ice age when erupting lava was cooled rapidly by the cold ground, are located in central Mexico. Despite being the only phenomenon of its kind in the American continent (there are similar formations in Hawaii, New Zealand, Japan and Ireland), they are still relatively unknown amongst foreign tourists. Those who make the journey from Mexico City, about 2.5 hours by car, are rewarded with a unique experience of seeing one of the most incredible natural formations in North America.
