Hi The Lost City School was in Cherokee County. It was near Tallequah. The site no longer exists, but I know my mother went to school there around 1908/10. I think there was a town or settlement of the same name there. I took my mom back there in the late 70's, we could not get there because our car could not ford a creek to get into the area and she was too frail to walk the couple of miles to get there. Jan Paul
