The United States Forest Service (USFS) Tuesday gave the green light to a 1,700-acre expansion of the West Elk coal mine 10 miles east of Paonia on Colorado’s Western Slope. West Elk owner Arch Coal, based in St. Louis, Mo., praised the decision for its job-saving potential. Environmental groups blasted the USFS ruling for its possible industrialization of the pristine Sunset Trail roadless area adjacent to the West Elk Wilderness Area.
