<br /> <br />I <br />, <br />I <br />I <br />r <br /> <br />mineral product, averaging close to 50 million <br />barrels a year. Natural gas production is <br />increasing and the various natural gas liquids- <br />chiefly natural gasoline-and liquefied petroleum <br />gases such as propane and butane are produced <br />in greater profusion each year. <br />The Rangely oilfield in Rio Blanco County <br />and the Adena field in Morgan County together <br />produced more than half the petroleum reported <br />for the entire State in 1960. At least 16 other <br />counties shared in the remaining output. <br /> <br />Bituminous Coal <br /> <br />Metallurgical coal from Colorado's southern <br />coalfield is shipped to a steel mill at Geneva, <br />Utah, or consumed within the State at a steel <br />plant in Pueblo. The rest of the State's coal <br />output, recently averaging well over 3 million <br />tons, is marketed chiefly within the State for <br />generation of electric power or heating. Pro- <br />duction is holding steady at 3.5 million tons <br />annuall y and is expected to grow as power <br />consumption increases. <br /> <br />Oil Shale <br /> <br />Northwestern Colorado contains the greatest <br />accumulation of oil shale in North America. <br />Some technicians claim that methods already <br />devised and tested could mine and process this <br />rock to obtain products substantially equivalent <br />to those that could be recovered from about a <br />trillion barrels of petroleum. Costs are such <br />however, that large-scale commercial production <br />is not expected ir: the near future. <br /> <br />Other Mineral Products <br /> <br />Carbon dioxide is produced as a gas along <br />wi th natural gas or oil in certain wells and often <br />is wasted to the air. Two plants, in Bent and <br />Montezuma Counties, now process carbon di- <br />oxide from wells in Las Animas and Montezuma <br />Counties, and market it as dry ice and as liquid <br />carbon dioxide. Peat production in Boulder, <br />Gilpin, and Teller Counties is increasing but <br />it is being used only as an admixture in fertil- <br />izers or as a soil conditioner. <br /> <br />Workers on the assembly line of the Western Division, <br />Clifton Precision Products Company put together a rotary <br />component called a synchro. The highly industrial re- <br />gion around Pikes Peak lists skilled workers as its most <br />important "natural resource." <br /> <br />41 <br />
