The Toluca Coal Mine marker is the Site of the Devlin Coal Company, which from 1893 to 1924 employed 771 workers, most of them Italian immigrants. At the height of production (1905) the mine produced 379,000 tons of coal. After the mine closed in 1924, the two large slag heaps became local landmarks known as the "Jumbos," and were climbed by children until constant erosion made them unsafe. An agreement between the City Council of Toluca and the Ill Department of Natural Resources promoted the repair and restoration of the Jumbos, and now they are surrounded by a city park.
