Colorado Fuel and Iron: Company Mines

Mines of the Colorado Fuel and Iron Company


This exhibit showcases the numerous mines of the Colorado Fuel and Iron Company and its predecessor companies: Central Colorado Improvement Company, Southern Colorado Coal & Town Company, the Colorado Fuel Company, the Colorado Coal and Iron Company, The Grand River Coal & Coke Company and the Denver Fuel Company.

CF&I created an important industrial base for the economic growth of Colorado. Capital and labor was brought to Colorado by CF&I and numerous communities were built to support the heavy industry of CF&I. As the first vertically integrated corporation West of the Mississippi, CF&I was essential in the development of agriculture, transportation, secondary manufacturing, and energy production in the region. None of it was possible, however, without the CF&I mines in Colorado, New Mexico, and Wyoming. CF&I also had mines in Oklahoma and Utah, but their impact was much less than the coal and iron mines. In addition to coal and iron, CF&I also had lime quarries and a fluorspar mine to help their vertically integrated business model of producing quality steel, coke, and heating coal.

A lot of focus and attention has been given to the coal mines of CF&I so this database strives to also include the important developments of the mines that produced lime, iron, and fluorspar.
