Description: Coal was mined in this region and transformed into coke in beehive ovens. Almost pure carbon, coke burns hotter than coal and was crucial to the success to Pittsburgh's steel marking.
One of the largest coking complexes was Adelaide, founded by Henry Clay Frick in 1888 and named for his wife. By 1910 it consisted of a coal mine, 375 coke ovens and housing for employees. It stretched from this area to nearly one mile downstream where a few partial ovens remain. In 1916, at preak production, 223,908 tons of coal were mined here and reduced to 149,270 tons of coke.
