Devils Tower

The tower rises 264 metres from its base in hexagonal and pentagonal columns, formed when magma cooled and contracted underground and the softer sedimentary rock around it eroded away - the columns are among the largest of their kind anywhere. It was made the first national monument in 1906. More than twenty Plains nations hold it sacred under names including Bear Lodge, and the origin story common to several involves children pursued by a bear, the rock rising to save them and the bear's claws cutting the flutes. The Park Service asks climbers to voluntarily refrain during June, when ceremonies take place. The name Devils Tower came from a mistranslation.
