Billed as covering everything from "Alzada to Zortman", the Montana Place Names Companion website tells the story of Montana's place names. The project began years ago at the reference desk at the Montana Historical Society Research Center in Helena when a patron called about the origin of a mountain peak name. Over the years, a team of dedicated individuals began to compile thousands of pieces of information about cities, rivers, and mountains across the Big Sky state. Now all of this material can be found here, courtesy of the National Resource Information System at the Montana State Library. Visitors can select a place name from the drop-down menu, type in a keyword, or click on the interactive map of the state. First-time visitors may wish to start by looking at Absarokee, Porcupine Butte, and Swimming Woman Creek.
