Wilderness conservation took a hit as part of this year’s federal budget compromise. A rider slipped into the bill at the last minute has put millions of acres of land back on the table for oil and gas drilling. One of those places is South Shale Ridge in western Colorado. The area is not federally protected wilderness. So the conservation-minded Interior Department had floated a different term for places like it, “wild lands.” But that definition is now up in the air.
