Lonaconing Furnace, also known as The George's Creek Coal and Iron Company Furnace No. 1, is a historic iron furnace in Lonaconing, Allegany County, Maryland, United States. It is a truncated square pyramid constructed of sandstone, 50 feet (15 m) high, 50 feet square at the base, and 25 feet square at the top. It first produced iron in 1839, then the iron operation was abandoned in the mid-1850s, the Loncaconing Furnace complex included a top house, molding house, engine house, and two hot-air furnaces for heating the blast. None of these ancillary structures remains. It played a significant role in demonstrating that both coke and raw bituminous coal could be used as fuels in the manufacture of iron. It is known as "the first coke furnace, whose operation was successful, erected in this country."Lonaconing Furnace was listed on the National Register of Historic Places in 1973.

The Big Vein refers to a 14-foot (4.3 m) thick seam of bituminous coal discovered in the Georges Creek Valley of Western Maryland in the early 19th century. This coal vein became famous for its clean-burning low sulfur content that made it ideal for powering ocean steamers, river boats, locomotives, steam mills, and machine shops. By 1850, almost 30 coal companies were mining the valley, extracting more than 60 million tons of coal between 1854 and 1891. The Consolidation Coal Company, established in 1864 and headquartered in Cumberland, Maryland became one of the largest bituminous coal companies in the eastern United States and Cumberland had financial connections that reached beyond Washington, D.C. and Baltimore to New York and London.

Georges Creek Valley is located in Allegany County, Maryland along the Georges Creek. The valley is rich in wide veins of coal, known historically as "The Big Vein." Coal was once extracted by deep mines but is only mined today through surface mining. The Georges Creek Valley was once a major center for the US coal industry.
