Hauling Ore from the Cranberry Mine
High grade magnetite iron ore was found at the base of Roan Mountain near Cranberry, NC after the War of 1812. A "bloomery", or iron smelter, was built at Cranberry in 1820 to process the ore and supply iron to the Confederacy during the Civil War. In 1875 Ario Pardee formed the Cranberry Iron & Coal Company to bring iron ore 34 miles from the Cranberry Mine to the Cranberry Furnace in Johnson City for smelting. A 3-foot gauge line was completed to Cranberry, NC in 1882. The magnetite ore was mined from 840,000,000 year old metamorphic rock called Epidote Gneiss. Between 1882 and 1920 over 1,250,000,000 tons of iron ore was taken from the Cranberry Mine.
It is comprised of banded epidote (green), amphibole (black), quartz (white) and magnetite (metallic). The magnetite is named for its strong natural magnetism. The rocks in this display were recovered from Buffalo Creek. They were likely considered low grade and were used to protect the pilings of the original bridge.
