Prismas Basálticos | ©Guillermo Palacios  (Huasca, Hidalgo, Mexico)

These basaltic prisms are located in the state of Hidalgo, Mexico, just only an hour and a half from the city of Mexico. It is a natural rock formation which was formed millions of years ago by the rapid cooling of lava; the stunning prisms are characterized by variations in gray and black color, besides having hexagonal shapes, pentagonal and quadrangular. The larger columns have a height of 40 meters.
