Deep beneath the earth's surface in Mexico lie some of the most spectacular natural wonders - Naica Crystal Cave and Giant Crystal Cave! These caves boast giant selenite crystals, some reaching up to 36 feet tall and weighing over 55 tons! The crystals formed over millions of years as mineral-rich water seeped into the caves and slowly evaporated, leaving behind these breathtaking formations. #caves #crystalgrowth #selenite #naturalwonders @knowledge-first
