A massive stone rising over 650 feet out of the flat ground of Guatape, Colombia, the Piedra de Penol or El Peñon de Guatape, was once worshiped by the Tahamies Indians.
By the 1900s, the massive 10-million-ton rock was seen by local farmers as a nuisance, a giant version of the rocks that the farmers regularly dug out of their fields. In 1954 a group of friends — supposedly at the urging of a local priest — climbed the rock using a series of boards wedged into a crack. These were the first people known to have climbed El Peñon de Guatape.
Climbing the huge stone took five days, but the top of the rock revealed beautiful views and a new species of plant, Pitcairma heterophila. The rock soon became a modest tourist attraction.
