Coal Mining in Colorado | Articles | Colorado Encyclopedia
The Advent of Industrial Coal. The earliest coal mining in Colorado took place in the late 1850s near the fledgling town of Denver, but industrial development of the state's coal resources awaited the arrival of William Jackson Palmer in the late 1860s. Over the next two decades, Palmer turned coal into Colorado's most important commodity.
