Hill City is home to the Black Hills Museum of Natural History, which came out of the vision of the Black Hills Institute for Geological Research. The museum was incorporated in 1992. The collection on display includes dinosaurs, fossil fishes, mammals, birds, reptiles, and fossil invertebrates, as well as gemstones, minerals, and meteorites. The highlight of the collection is the "Tyrannosaurus rex" specimen named "Stan" which is one of the most compete skeletons unearthed with 65% of the bones unearthed. The museum is also a leading contributor to Hill City's Natural History Days celebration that focuses on fun and education, with guest speakers, and a fossil hunt for children.
