Shoshone Bird Museum of Natural History

The Shoshone Bird Museum of Natural History features birds from all corners of the globe, meticulously mounted and displayed to showcase their intricate colors and patterns. Also on view are butterflies of the world, fish and dinosaur fossils, animals from around the globe, pioneer artifacts, Stone Age artifacts,  American Indian artifacts, and thousands of artifacts from cultures ranging from Africa to South America, among many other displays. This wealth of exhibits has earned the museum the nickname “The Smithsonian of the Desert” and is a must-see destination for any natural history enthusiast.

Richard Arthur Olsen Museum of Natural History

Carrying on our founder’s mission to educate those who want to learn more about natural objects, worldwide histories, and cultures of the past, Idaho’s Mammoth Cave recently expanded with the opening of a second museum, dubbed the Richard Arthur Olsen Museum of Natural History that he planned to share before his passing in 2019. This new addition to the complex offers visitors an even more comprehensive view of the natural and cultural history of the world. Exhibits include an amazing array of fossils, rocks, gemstones, animals, and cultural artifacts worldwide, making it one of the most facinating things to do in Idaho.
