Mapping the Rise of the Ku Klux Klan

Mapping the Second Ku Klux Klan, 1915-1940 is an animated timeline map showing the rise of klaverns in the United States between 1915 and 1940.

The Virginia Commonwealth Library says that the first 'Klan of Reconstruction' and the third 'Klan of the Civil Rights era' were both mainly concentrated in the Deep South. This animated map shows how the second Klan spread across the United States.

If you press the play button on the timeline the map shows the opening of klaverns during each year during the period. You can also manually move the timeline to show the geographical spread of the klaverns which opened in any specific year.

It seems that you can only view the klaverns opened for a specific year. It would be useful to be able to also view the total number of Ku Klux Klan klaverns which opened during the entire period of the map. This option however is missing from the map.
