Significance: Considered among the world's richest mineral deposits, the Pittsburgh seam of coal underlying portions of Fayette and Westmoreland Counties in southwestern Pennsylvania produced metallurgical coke of exceptional quality. Covering nearly 147 square miles, the seam's thickness, nearness to the surface, friable structure, and chemical attributes made Connellsville coke the ideal fuel for late nineteenth and early twentieth century iron furnaces. Combined with the adjacent Klondike fields, the region contained the world's largest complex of beehive coking ovens.
