The word “fracking” has come to mean drilling in general for oil and gas-- and a major concern for communities and environmentalists in Colorado and elsewhere. In reality the process of hydraulic fracturing is a specialized procedure used to create cracks in shale deposits thousands of feet underground which in turn releases trapped natural gas. There are hundreds of fracked wells in Garfield County. Often you can see them from the highway. Recently Aspen Public Radio got a tour of a fracking operation run by WPX Energy near Parachute.
