Spielberg put the mothership behind this rock in 1977 and turned a remote Wyoming monolith into one of the most recognisable shapes on earth; visits jumped and never came back down. The visitor center keeps a display about it. Worth holding both ideas at once — it's a film set to most of the world and a sacred site to more than twenty Plains tribes, who call it Bear Lodge.

There is almost no light out here. Stay after the prairie dogs have gone to bed, lie back on the hood, and look up: the tower goes to silhouette and the Milky Way runs directly over the top of it.
