The Buena Vista Furnace is one of three iron furnaces that once operated in the Blacklick Creek Valley. The furnace was constructed in 1847 and operated on and off until 1856. The cold blast furnace produced 400 tons of pig iron a year. About 61 men and boys and 30 mules labored at the furnace. The furnace is located 1/2mile downstream of the Route 56 Bridge and about 3 miles est of the Heshbon Access Area.
