This exhibit is in honor of the Idaho Sesquicentennial celebration and will focus on historical events, people, places and journeys relative to the early Idaho territorial period and Packer John’s Cabin where meetings were held and important Idaho documents were signed. The exhibit is open to the public and free. Plan now to make a visit to this fun and informative exhibit this summer. The exhibit opens Saturday, July 13, 2013 and will be open weekends throughout the summer. Check the ACHS Event Calendar for changes in hours.
