A hand-drawn map of the mines at Starkville, Colorado, owned by the Trinidad Coal and Coking Company. General Manager C. C. Wheeler and Secretary/Treasurer E. Wilder worked out of the Topeka, Kansas, offices. The map (attributed to surveyor William H. Leffingwell) and notations were written by Isaac Tichenor Goodnow and expanded into a piece for the Kansas City Review of Science and Industry and the Scientific American Supplement on November 24, 1883 titled 'The Trinidad Coal Mines'. Goodnow describes traveling by train to "find Starkville, a sort of suburb to Trinidad, and the site of a remarkable coal mine, stopping an hour and a half to examine it." The map and notations were presumably made on this trip. Goodnow writes that laborers outside the mine were paid $2 per day, while those working inside the mine were paid $3 per day. The mine was the subject of a U. S. Supreme Court case decided on November 17, 1890, and the site of an explosion on October 8, 1910 that killed 56 men.
