The Denver Post: Members of the Ku Klux Klan lived in every corner of Denver during the racist, anti-immigrant hate group’s brief reign in the 1920s, a new map of the members’ addresses shows.

Staff at History Colorado spent more than 300 hours logging by hand and mapping each address listed in the nearly 30,000 entries in two ledgers in the organization’s collection that document the membership of the Denver KKK chapter from approximately 1924 through 1926.

The mapping project followed the digitization of the ledgers’ contents and their publication online this spring, making the information easily accessible to the public for the first time.
