On this day in 1866, Frederick Douglass visited Ypsilanti, Michigan, a hub of the Underground Railroad with a sizable Black community. He spoke about Lincoln’s assassination and shared anecdotes from his meetings with the President during the Civil War. And today in 1881, Julius Ropes discovered gold near Ishpeming, Michigan. Two years later, he opened the only profitable gold mine east of the Mississippi River, which operated until 1991.
