An aerial view of Selma Hall in 1964 showing the Mississippi River beneath the Jefferson County bluff. Thomas C. Reynolds and Gratz Brown rowed from the riverbank to a sand bar for their duel in 1856. The home is southeast of Festus and Crystal City. In 1856, the nearest town was Herculaneum. The Union Pacific Railroad now owns it and uses it for executive retreats. It is not open to the public. Photo by Renyold Ferguson of the Post-Dispatch
