Devils Tower

Wyoming, USA

Rising sharply from the Black Hills of northeastern Wyoming, Devils Tower is visible for miles around.¹ The top of the formation comprised of reddish sandstone and siltstone is more than 1,250 feet above the surrounding terrain, and although geologists are unsure of exactly how the tower formed, they agree it has an igneous origin.^{2 3}

President Theodore Roosevelt declared Devils Tower the first national monument in 1906. Before that time, the site was known as Devil’s Tower, but the accidental omission of the apostrophe in the official proclamation led to the current spelling.
