Organized in 1972, the Whitman County Historical Society strives to preserve the history and cultural heritage of our region. To do this the society has developed programs designed to meet a variety of interests in the area. The society owns two museums, publishes a newsletter and a historical journal, and maintains a growing archival collection.
The Historical Society has a number of ongoing projects including the Perkins House in Colfax, Washington, the oldest house in the county; the WCHS Archive located in the Gladish Community Center in Pullman, Washington; and the Roy Chatters Newspaper and Printing Museum, located in Palouse, Washington.
The Society sponsors an Ice Cream Social the last Sunday in June.
