Canton, MD 1939

Today we think of the Canton area of Baltimore as a shipping center, or a place to buy a condo, but 67 years ago its most obvious feature was oil refineries. Baltimore imported oil for its own use and also exported refined petroleum products to the rest of the Atlantic coast. In 1939 Baltimore hosted four refineries and three receiving & blending stations. Canton's refineries have been shut down for decades, but traces remain, though they're rapidly disappearing.
