Tony, that's the same place. In those days, the eastern part of present-day Clay County was in Greene County. Chalk Bluff was a thriving community then. A post office was established there in 1850, and by 1861 the town and surrounding area had a population sufficient to recruit a full company of infantry -- known as the "Chalk Bluff Rebels" -- which became Co. F, 18th (Marmaduke's) Arkansas Infantry. The town was pretty much destroyed during the war, and by 1868 the post office was officially discontinued.
