The historical record of North Dakota coala dark brown to black combustible rock of organic origin formed over millions of years by the partial decomposition of... goes back as far as the early 1870s. Early inhabitants and explorers of North Dakota used ligniteBrownish-black coal in which the alteration of vegetal material has proceeded further than in peat but not so far as... coal long before the coal industry took root. With few available trees, Native American tribes in the area burned lignite coal as a substitute for firewood.
When the Lewis & Clark expedition came through North Dakota in 1804, they were instructed to make note of available resources. Lewis made note of coal seams multiple times in his journal.
“There is more appearance of coal today than we have yet seen. The stratas are 6 feet thick in some instances; the earth has been birnt in many places, and always appears in stratas on the same level with stratas of coal.”

In 1873, General Custer escorted a group of entrepreneurs from Bismarck to Sims, North Dakota, where they had noticed several visible coal veins and hoped to start a mine. Though the first group to mine at Sims ultimately failed, other successful mines popped up throughout the state. By 1900, over 70 coal mines were operating in North Dakota. While some were larger commercial mines, others were smaller “wagon mines.”
