The No. 9 Coal mine was opened in 1855, but its origin traces back ten years earlier. A large anthracite coal deposit called Mammoth Vein was the focus for most mining in the Lehigh Valley. Major mine systems in the Summit Hill area produced a great deal of coal from the Vein. Unfortunately, the quarry had to be abandoned due to flooding. Mining companies decided to attempt another drilling into Mammoth Vein.
