SAGAMORE COALFIELD

This was a small coalfield on the eastern edge of Armstrong County in the vicinity of Cowanshannock Creek and the North Branch of Plum Creek. It was named for the first large coal mining enterprise in the area. Mining was in the Upper Freeport and Lower Freeport coal seams. From what I can see, coal mining in the Sagamore Coalfield has ceased.
