History of anthracite coal mining in Pennsylvania History of anthracite coal mining in Pennsylvania There are two types of coal found in Pennsylvania: anthracite (the “hard coal” found in Northeastern Pennsylvania below the Allegheny Ridge southwest to Harrisburg; also called “stone coal”, “rock coal” in the 1800s) and bituminous (“soft coal”, found west of the Allegheny Front escarpment). Anthracite coal is a natural mineral with a high carbon and energy content that gives off light and heat (produced energy) when burned, making it useful as a fuel. It was possibly first used in Pennsylvania as a fuel in 1769, but its real history begins with a documented
Burns Bog salmon-bearing creeks. Burns Bog is also a major carbon sink. Since organic matter decomposes at a very slow rate in the bog, carbon stays in the bog. High acidity and the waterlogged conditions of peatlands such as Burns Bog prevent complete decomposition of fixed carbon. This prevents the carbon from escaping into the atmosphere. European scientists state that an area of peatland the size of a soccer field stores as much carbon as driving a family car around the world three times. Burns Bog was formed at the end of the last ice age, which was 10,000 years ago. At
