Situated in northeastern Wyoming, Devils Tower stands out as the inaugural national monument in the United States. President Theodore Roosevelt bestowed this title upon it on September 24, 1906, utilizing the recently enacted Antiquities Act. Soaring impressively to a height of 867 feet from its base, the tower showcases a remarkable geological marvel, crafted by an igneous intrusion and renowned for its distinct hexagonal pillars. In the 1977 film Close Encounters of the Third Kind, this formation played a pivotal role, serving as both a narrative element and the backdrop for its climactic sequences.
