Vital, active, informed chapters are the heart of the Wyoming State Historical Society. The WYSHS is a statewide organization which seeks to work with local history groups throughout Wyoming. Most members of the Wyoming State Historical Society are members of a chapter as well. Most WYSHS chapters are organized as county Historical Societies, however in some cases, there may be more than one affiliated chapter in a county.
