This small coal field (approximately 66 square miles), located in the northwestern corner of Maryland, was once served by the Baltimore and Ohio Railroad's Kendall Branch, also known as their Confluence and Oakland Branch. However, the construction of a dam and Youghiogheny Lake obliterated all of this. Mining was never as intense as other coalfields, but there were several mines, like the Rayland Mine on the edge of Friendsville; or the tiny 2 man Steele Mine, which had only natural ventilation, shot coal "off the solid," and pushed the coal cars out by hand. There was one large mine, and possibly some company housing that went with it - the McCullough Coal Corporation's McCullough Mine No. 1 - which was opened from 1915 until 1942. The McCullough Mine was in the Upper Freeport seam of coal, and the Lower Kittanning and Waynesburg seams have also been mined in the Lower Youghiogheny Coal Field. The Upper Freeport coal (~14,500 - 15,500 Btu/lb here) can be considered a metallurgical coal in this region, and the Lower Kittanning coal can be washed in a preparation plant to make a coking coal as well. Apparently, underground coal mining began in the late 1800s and lasted until the 1940s. Then strip mining became the norm, especially during the energy crises of the 1970s. After that coal mining in the Lower Youghiogheny Coalfield declined. 217,213 short tons of coal were mined in 1982.
