Driving south from Ada, Oklahoma to Madill, OK you will pass through Tishomingo, OK. Tishomingo is the capitol of the Chickasaw Indian Nation. The Chickasaw Nation is one of the Five civilized tribes that were moved out of the southeastern US onto reservations in Oklahoma in the mid 1800's. In 1898 they began construction on this capitol building. It is built out of granite. By my calculations, some of the stones weigh 2500-3000 pounds each.
We got there too late to tour the facility, so the history on the granite markers will have to do for now.
